Per- and polyfluoroalkylated substances (PFAS) are at the heart of current environmental concerns, due to their persistence, mobility and potential effects on human health and ecosystems.<\/p>\n
To meet the growing demands of environmental monitoring, our partner, Wellington Laboratories (Canada), has recently developed a new PFAS analytical mixture: ISO 21675-LSSA<\/a>. This mixture is specifically formulated to meet the requirements of ISO 21675:2019, relating to the analysis of PFAS by LC-MS\/MS in aqueous matrices. <\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_4,3_4″ _builder_version=”4.27.3″ _module_preset=”default” background_color=”rgba(200,198,198,0.08)” global_colors_info=”{}”][et_pb_column type=”1_4″ _builder_version=”4.27.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” ul_font_size=”14px” header_2_text_color=”#4B6587″ header_3_font=”|600|||||||” header_3_line_height=”1em” sticky_limit_top=”none” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”3_4″ _builder_version=”4.27.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.4″ _module_preset=”d3172fc8-ec52-49d0-b82c-111dc82dea35″ global_colors_info=”{}”]<\/p>\n ISO 21675-NSS<\/strong> (Native Stock Solution) contains unlabelled (native) compounds.
