Faced with the challenges posed by PFAS, it is essential to analyse these substances using analytical standards in order to guarantee public safety. This is why BCP Instruments is the exclusive supplier in France and Belgium of <a href=\"#melanges_isomeres_PFAS\" title=\"br-PFOA &amp; br-PFNA\">high-precision PFAS isomer mixtures<\/a> prepared by Wellington Laboratories.  <\/span><\/p>\n<h3><span>Why analyse mixtures of linear and branched isomers?<\/span><\/h3>\n<p>PFAS isomers are structural variants of the same molecule, play a key role in several areas:<\/p>\n<ul>\n<li><strong> Identifying sources of pollution:<\/strong> Isotopic signatures help to trace industrial or domestic discharges.<\/li>\n<li><strong> Environmental characterisation:<\/strong> the distribution of isomers affects their transport in soils, their accumulation in organisms and their behaviour in aquatic ecosystems.<\/li>\n<li><strong>Regulatory monitoring:<\/strong> PFAS monitoring in water, air and soils requires precise isomer differentiation.<\/li>\n<li><strong>Toxicological research:<\/strong> some isomers have distinct biological and eco-toxicological properties, requiring detailed analyses.<\/li>\n<\/ul>\n<h3><span>A complete range dedicated to environmental analysis<\/span><\/h3>\n<p>To meet the challenges of precision and compliance, Wellington has developed two new quantitative isomeric mixtures of PFOA and PFNA: br-PFOA and br-PFNA. These blends, with a chemical purity of over 98%, contain linear and branched isomers, faithfully reflecting the technical materials. They are therefore designed to guarantee optimum analysis results.  <\/p>\n<p>In addition, this initiative complies with the strict methods of the US EPA (1633, 533 and 537.1), which require accurate identification and quantification of isomers for a complete assessment of PFAS exposure.<\/p>\n<h3><span>The advantage of prepared blending solutions<\/span><\/h3>\n<p><span>For analytical laboratories, using mixtures of isomers prepared by Wellington offers several advantages:<\/span><\/p>\n<ul data-spread=\"false\">\n<li><strong>Save time and resources:<\/strong> ready-to-use mixes allow laboratories to concentrate on analysis without having to prepare their own mixes.<\/li>\n<li><strong> Regulatory compliance:<\/strong> these mixtures comply with the strict requirements of standard methods.<\/li>\n<li><strong> Reliable results:<\/strong> high purity and precise proportions guarantee reproducible and reliable data.<\/li>\n<\/ul>\n<h3><span>A solution tailored to the needs of laboratories<\/span><\/h3>\n<p><span>By incorporating these mixtures into their protocols, laboratories can meet the growing demand for comprehensive and rigorous analysis of PFAS, while optimising their analytical performance. In this way, these standards provide a solid basis for accurately identifying the different isomers present in the environment or in biological samples, contributing to a better understanding and management of these persistent pollutants. <\/span><\/p>\n<h3>Contact us<\/h3>\n<p>BCP Instruments puts its expertise at the service of French and Belgian laboratories to help you with your environmental analyses. <strong>Contact us today<\/strong> to find out how our solutions can meet your specific needs.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row module_id=&#8221;melanges_isomeres_PFAS&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.27.2&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;d3172fc8-ec52-49d0-b82c-111dc82dea35&#8243; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h2>New blends of linear and branched native PFAS are available: br-PFOA &amp; br-PFNA.
