The PVC from old window frames could, in principle, be well recycled and reused in significant proportions in new window frames, were it not for the problem with unwanted heavy metals. &lt;\\\/p&gt;\\n&lt;h5&gt;Solution&lt;\\\/h5&gt;\\n&lt;p&gt;There are methods to extract heavy metals from shredded old window material. The task of Analytik Service Obernburg is the regular verification that this has been successfully achieved. For this purpose, a portion of the recyclate is chemically digested. The heavy metal contents in the corresponding solution are quantified using inductively coupled plasma emission spectroscopy (ICP-OES). From this, it can be deduced at what concentration the regranulate can be added to the process without exceeding limit values. Similarly, due to the high detection sensitivity of the method, it is possible to characterize sections of a new window frame with recyclate admixture regarding traces of heavy metals.     &lt;\\\/p&gt;\\n&lt;h5&gt;Industries &amp; Applications&lt;\\\/h5&gt;\\n&lt;ul&gt;\\n&lt;li&gt;Construction Industry&lt;\\\/li&gt;\\n&lt;li&gt;Plastics Processors&lt;\\\/li&gt;\\n&lt;li&gt;Plastics Recyclers&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;h5&gt;Analysis Objectives&lt;\\\/h5&gt;\\n&lt;ul&gt;\\n&lt;li&gt;Quality Assurance&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;h5&gt;Materials&lt;\\\/h5&gt;\\n&lt;ul&gt;\\n&lt;li&gt;PVC Regranulate&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;h5&gt;Analysis Methods&lt;\\\/h5&gt;\\n&lt;ul&gt;\\n&lt;li&gt;ICP-OES (Inductively Coupled Plasma Emission Spectroscopy)&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;h5&gt;Advantages&lt;\\\/h5&gt;\\n&lt;p&gt;Abrasion and wear testing devices make it possible to investigate wear on technical textiles in the laboratory.

Based on the results of these tests, the suitability and quality of materials can be assessed.  &lt;\\\/p&gt;\\n&lt;p&gt;&lt;img class=\\&quot;alignnone wp-image-35845 size-full\\&quot; src=\\&quot;https:\\\/\\\/aso-labor.de\\\/wp-content\\\/uploads\\\/2025\\\/05\\\/Abb-1-Nachweis-von-Schwermetallen-mit-Hilfe-von-ICP-OES.jpeg\\&quot; alt=\\&quot;\\&quot; width=\\&quot;558\\&quot; height=\\&quot;372\\&quot;&gt;&lt;\\\/p&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;&lt;strong&gt;Fig 1: &lt;\\\/strong&gt;Detection of heavy metals using ICP-OES&lt;\\\/p&gt;\\n&lt;p&gt;&lt;img class=\\&quot;alignnone size-full wp-image-35844\\&quot; src=\\&quot;https:\\\/\\\/aso-labor.de\\\/wp-content\\\/uploads\\\/2025\\\/05\\\/Kerncoextrudierter-Fensterprofilabschnitt.jpeg\\&quot; alt=\\&quot;\\&quot; width=\\&quot;630\\&quot; height=\\&quot;317\\&quot;&gt;&lt;\\\/p&gt;\\n&lt;p class=\\&quot;p1\\&quot;&gt;Core co-extruded window profile section Layer co-extruded window profile section&lt;\\\/p&gt;\\n&quot;,&quot;item_icon&quot;:{&quot;value&quot;:&quot;far fa-file-pdf&quot;,&quot;library&quot;:&quot;fa-regular&quot;},&quot;_id&quot;:&quot;c0ff726&quot;,&quot;content_type&quot;:&quot;toggle-content&quot;,&quot;saved_section&quot;:null,&quot;saved_template&quot;:null,&quot;toggle_custom_id&quot;:&quot;&quot;},{&quot;toggle_title&quot;:&quot;Particle Size Analysis&quot;,&quot;toggle_content&quot;:&quot;&lt;h4&gt;Particle Analysis \\u2013 Characterization of Powders and Suspensions&lt;\\\/h4&gt;\\n&lt;h5&gt;Problem Statement&lt;\\\/h5&gt;\\n&lt;p&gt;The processing properties of a powder or suspension critically depend on the particle size, particle shape, and surface chemistry of the particles. Thus, one powder may flow finely, while another tends to clump. Particles that are too large can clog filters, while particles that are too small can cause significant dust formation during further processing. This is just a small selection of issues attributable to different particle properties.   &lt;\\\/p&gt;\\n&lt;h5&gt;Solution&lt;\\\/h5&gt;\\n&lt;p&gt;At Analytik Service Obernburg, various analytical methods are used for particle characterization, which will be discussed in more detail below.&lt;\\\/p&gt;\\n&lt;h5&gt;Industries &amp; Applications&lt;\\\/h5&gt;\\n&lt;ul&gt;\\n&lt;li&gt;Medical Technology&lt;\\\/li&gt;\\n&lt;li&gt;Paint Manufacturers&lt;\\\/li&gt;\\n&lt;li&gt;Compounders&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;h5&gt;Analysis Objectives&lt;\\\/h5&gt;\\n&lt;ul&gt;\\n&lt;li&gt;Particle Size&lt;\\\/li&gt;\\n&lt;li&gt;Particle Shape&lt;\\\/li&gt;\\n&lt;li&gt;Agglomeration Tendency&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;h5&gt;Materials&lt;\\\/h5&gt;\\n&lt;ul&gt;\\n&lt;li&gt;Powders&lt;\\\/li&gt;\\n&lt;li&gt;Suspensions&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;h5&gt;Analysis Methods&lt;\\\/h5&gt;\\n&lt;ul&gt;\\n&lt;li&gt;Laser Diffraction&lt;\\\/li&gt;\\n&lt;li&gt;Scanning Electron Microscopy (SEM-EDX)&lt;\\\/li&gt;\\n&lt;\\\/ul&gt;\\n&lt;h5&gt;Example \\u2013 Particle Size Distribution&lt;\\\/h5&gt;\\n&lt;p&gt;The particle size distribution is determined using laser diffraction. Particles between 0.1 \\u03bcm and 2000 \\u03bcm can be measured. A distribution curve is obtained, from which the particle size can be read, as well as various statistical values describing the distribution. These values can be directly used for validating the manufacturing process in quality assurance. The test is performed on the powder dispersed in water. By measuring with and without ultrasound, a distinction can be made between agglomerates and primary particles.     &lt;\\\/p&gt;\\n&lt;h5&gt;Example \\u2013 Particle Shape&lt;\\\/h5&gt;\\n&lt;p&gt;Various microscopic measurement methods are available for investigating the particle shape \\u2013 from light microscopy and electron microscopy (SEM) to atomic force microscopy (AFM). This allows not only the shape of the particles to be characterized, but also their fine surface structure. Both are crucial for the interaction between the particles (e.g. tendency to agglomerate). If required, the shape of the particles can be quantified by subsequent computer image analysis.&lt;\\\/p&gt;\\n&lt;h5&gt;Example \\u2013 Surface Chemistry&lt;\\\/h5&gt;\\n&lt;p&gt;Just like particle morphology, surface chemistry (moisture, foreign substances such as oils, or targeted surface modifications) also influences the properties during processing or the distribution of particles in the final product. Depending on the question, different chemical or spectroscopic methods are used here to detect changes in surface chemistry. &lt;\\\/p&gt;\\n&lt;h5&gt;Advantages&lt;\\\/h5&gt;\\n&lt;p&gt;The described methods allow for comprehensive characterization and visualization of particles in powders or suspensions.

The PVC from old window frames could, in principle, be well recycled and reused in significant proportions in new window frames, were it not for the problem with unwanted heavy metals. <\/p>\n<h5>Solution<\/h5>\n<p>There are methods to extract heavy metals from shredded old window material. The task of Analytik Service Obernburg is the regular verification that this has been successfully achieved. For this purpose, a portion of the recyclate is chemically digested. The heavy metal contents in the corresponding solution are quantified using inductively coupled plasma emission spectroscopy (ICP-OES). From this, it can be deduced at what concentration the regranulate can be added to the process without exceeding limit values. Similarly, due to the high detection sensitivity of the method, it is possible to characterize sections of a new window frame with recyclate admixture regarding traces of heavy metals.     <\/p>\n<h5>Industries &amp; Applications<\/h5>\n<ul>\n<li>Construction Industry<\/li>\n<li>Plastics Processors<\/li>\n<li>Plastics Recyclers<\/li>\n<\/ul>\n<h5>Analysis Objectives<\/h5>\n<ul>\n<li>Quality Assurance<\/li>\n<\/ul>\n<h5>Materials<\/h5>\n<ul>\n<li>PVC Regranulate<\/li>\n<\/ul>\n<h5>Analysis Methods<\/h5>\n<ul>\n<li>ICP-OES (Inductively Coupled Plasma Emission Spectroscopy)<\/li>\n<\/ul>\n<h5>Advantages<\/h5>\n<p>Abrasion and wear testing devices make it possible to investigate wear on technical textiles in the laboratory.

Thus, one powder may flow finely, while another tends to clump. Particles that are too large can clog filters, while particles that are too small can cause significant dust formation during further processing. This is just a small selection of issues attributable to different particle properties.   <\/p>\n<h5>Solution<\/h5>\n<p>At Analytik Service Obernburg, various analytical methods are used for particle characterization, which will be discussed in more detail below.<\/p>\n<h5>Industries &amp; Applications<\/h5>\n<ul>\n<li>Medical Technology<\/li>\n<li>Paint Manufacturers<\/li>\n<li>Compounders<\/li>\n<\/ul>\n<h5>Analysis Objectives<\/h5>\n<ul>\n<li>Particle Size<\/li>\n<li>Particle Shape<\/li>\n<li>Agglomeration Tendency<\/li>\n<\/ul>\n<h5>Materials<\/h5>\n<ul>\n<li>Powders<\/li>\n<li>Suspensions<\/li>\n<\/ul>\n<h5>Analysis Methods<\/h5>\n<ul>\n<li>Laser Diffraction<\/li>\n<li>Scanning Electron Microscopy (SEM-EDX)<\/li>\n<\/ul>\n<h5>Example \u2013 Particle Size Distribution<\/h5>\n<p>The particle size distribution is determined using laser diffraction. Particles between 0.1 \u03bcm and 2000 \u03bcm can be measured. A distribution curve is obtained, from which the particle size can be read, as well as various statistical values describing the distribution. These values can be directly used for validating the manufacturing process in quality assurance. The test is performed on the powder dispersed in water. By measuring with and without ultrasound, a distinction can be made between agglomerates and primary particles.     <\/p>\n<h5>Example \u2013 Particle Shape<\/h5>\n<p>Various microscopic measurement methods are available for investigating the particle shape \u2013 from light microscopy and electron microscopy (SEM) to atomic force microscopy (AFM). This allows not only the shape of the particles to be characterized, but also their fine surface structure. Both are crucial for the interaction between the particles (e.g. tendency to agglomerate). If required, the shape of the particles can be quantified by subsequent computer image analysis.<\/p>\n<h5>Example \u2013 Surface Chemistry<\/h5>\n<p>Just like particle morphology, surface chemistry (moisture, foreign substances such as oils, or targeted surface modifications) also influences the properties during processing or the distribution of particles in the final product. Depending on the question, different chemical or spectroscopic methods are used here to detect changes in surface chemistry. <\/p>\n<h5>Advantages<\/h5>\n<p>The described methods allow for comprehensive characterization and visualization of particles in powders or suspensions.

The PVC from old window frames could, in principle, be well recycled and reused in significant proportions in new window frames, were it not for the problem with unwanted heavy metals. <\\\/p>\\n<h5>Solution<\\\/h5>\\n<p>There are methods to extract heavy metals from shredded old window material. The task of Analytik Service Obernburg is the regular verification that this has been successfully achieved. For this purpose, a portion of the recyclate is chemically digested. The heavy metal contents in the corresponding solution are quantified using inductively coupled plasma emission spectroscopy (ICP-OES). From this, it can be deduced at what concentration the regranulate can be added to the process without exceeding limit values. Similarly, due to the high detection sensitivity of the method, it is possible to characterize sections of a new window frame with recyclate admixture regarding traces of heavy metals.     <\\\/p>\\n<h5>Industries &amp; Applications<\\\/h5>\\n<ul>\\n<li>Construction Industry<\\\/li>\\n<li>Plastics Processors<\\\/li>\\n<li>Plastics Recyclers<\\\/li>\\n<\\\/ul>\\n<h5>Analysis Objectives<\\\/h5>\\n<ul>\\n<li>Quality Assurance<\\\/li>\\n<\\\/ul>\\n<h5>Materials<\\\/h5>\\n<ul>\\n<li>PVC Regranulate<\\\/li>\\n<\\\/ul>\\n<h5>Analysis Methods<\\\/h5>\\n<ul>\\n<li>ICP-OES (Inductively Coupled Plasma Emission Spectroscopy)<\\\/li>\\n<\\\/ul>\\n<h5>Advantages<\\\/h5>\\n<p>Abrasion and wear testing devices make it possible to investigate wear on technical textiles in the laboratory.

Thus, one powder may flow finely, while another tends to clump. Particles that are too large can clog filters, while particles that are too small can cause significant dust formation during further processing. This is just a small selection of issues attributable to different particle properties.   <\\\/p>\\n<h5>Solution<\\\/h5>\\n<p>At Analytik Service Obernburg, various analytical methods are used for particle characterization, which will be discussed in more detail below.<\\\/p>\\n<h5>Industries &amp; Applications<\\\/h5>\\n<ul>\\n<li>Medical Technology<\\\/li>\\n<li>Paint Manufacturers<\\\/li>\\n<li>Compounders<\\\/li>\\n<\\\/ul>\\n<h5>Analysis Objectives<\\\/h5>\\n<ul>\\n<li>Particle Size<\\\/li>\\n<li>Particle Shape<\\\/li>\\n<li>Agglomeration Tendency<\\\/li>\\n<\\\/ul>\\n<h5>Materials<\\\/h5>\\n<ul>\\n<li>Powders<\\\/li>\\n<li>Suspensions<\\\/li>\\n<\\\/ul>\\n<h5>Analysis Methods<\\\/h5>\\n<ul>\\n<li>Laser Diffraction<\\\/li>\\n<li>Scanning Electron Microscopy (SEM-EDX)<\\\/li>\\n<\\\/ul>\\n<h5>Example \\u2013 Particle Size Distribution<\\\/h5>\\n<p>The particle size distribution is determined using laser diffraction. Particles between 0.1 \\u03bcm and 2000 \\u03bcm can be measured. A distribution curve is obtained, from which the particle size can be read, as well as various statistical values describing the distribution. These values can be directly used for validating the manufacturing process in quality assurance. The test is performed on the powder dispersed in water. By measuring with and without ultrasound, a distinction can be made between agglomerates and primary particles.     <\\\/p>\\n<h5>Example \\u2013 Particle Shape<\\\/h5>\\n<p>Various microscopic measurement methods are available for investigating the particle shape \\u2013 from light microscopy and electron microscopy (SEM) to atomic force microscopy (AFM). This allows not only the shape of the particles to be characterized, but also their fine surface structure. Both are crucial for the interaction between the particles (e.g. tendency to agglomerate). If required, the shape of the particles can be quantified by subsequent computer image analysis.<\\\/p>\\n<h5>Example \\u2013 Surface Chemistry<\\\/h5>\\n<p>Just like particle morphology, surface chemistry (moisture, foreign substances such as oils, or targeted surface modifications) also influences the properties during processing or the distribution of particles in the final product. Depending on the question, different chemical or spectroscopic methods are used here to detect changes in surface chemistry. <\\\/p>\\n<h5>Advantages<\\\/h5>\\n<p>The described methods allow for comprehensive characterization and visualization of particles in powders or suspensions. This enables the analysis of raw materials or products within the scope of quality assurance. The methods are also suitable for determining the cause of problems (e.g., during processing) in case of damage.
