| Abstract |
This quality control protocol is intended to serve as a guide to those laboratories employing fused silica capillary column (FSCC) gas chromatographic/mass spectrometric (GC/MS) techniques for the analysis of the extractable semivolatile priority pollutants. The document presents apparatus requirements and gives guidance for standards preparation, extract mixing, system setup and calibration. Qualitative and quantitative data including internal standard assignment, quantitation mass, relative retention times (RRT) values, interlaboratory and intralaboratory response factors (RF) values are also presented. This document provides a schedule for GC/MS system calibration requirements including: ion abundance calibration, column performance testing, sensitivity verification, system linearity, and injection technique reproducibility. This protocol does not provide guidance regarding sample extraction and workup; therefore, any quality control (QC) parameters related to this aspect of priority pollutant analysis are not addressed in this protocol. |
