ISO 17858:2007 specifies a method for the determination of dioxin-like tetra- to hepta-chlorinated biphenyls (PCBs) in waters and wastewaters (containing less than 1 % suspended solids) using high-resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS). The minimum levels at which the dioxin-like PCBs can typically be determined with no interferences present are specified. This method is "performance based". The analyst is permitted to modify the method to overcome interferences or lower the cost of measurements, provided that all performance criteria in this method are met. The requirements for establishing method equivalency are given.
Abstract
Overview
SIST ISO 17858:2010 (ISO 17858:2007) specifies a laboratory method for the determination of dioxin-like polychlorinated biphenyls (PCBs) in waters and wastewaters (matrices containing less than 1% suspended solids) using high-resolution gas chromatography / high-resolution mass spectrometry (HRGC/HRMS). The standard covers sample preparation through final quantification, defines minimum levels at which dioxin-like PCBs can typically be determined (when no interferences are present), and sets out performance criteria and requirements for establishing method equivalency. The method is explicitly performance-based, allowing analysts to adapt procedures to overcome interferences or reduce costs provided all performance criteria are met.
Key Topics and Technical Requirements
- Target analytes: Dioxin-like tetra- to hepta-chlorinated biphenyl congeners.
