Volatile Organic Compounds (VOCs) in water. Analytical Method Purge and Trap, Headspace (Static or Dynamic) - GC/MS or GC/PID (PBM). Introduction . This method is applicable to the quantitative determination of volatile organic compounds in water samples. Analysis for VH w6-10 is often conducted concurrently. Method Summary
Analysis of Volatile Organic Compounds in Water Using Static Headspace-GC/MS Abstract A static headspace (SHS) method was optimized for the determination of volatile organic compounds (VOCs) in water. Analysis was performed by GC/MS in simultane-ous scan/SIM mode. Using the trace ion detection mode on a MSD equipped

analysis combined with gas chromatography mass spectrometry for the analysis of 53 volatile organic compounds in river Aijiren Technology, waste Aijiren Technology and treated water samples down to 0.1 µg.L −1 concentration levels. They concluded that the content of VOCs in river water mainly correlates to the content of these compounds in waste Aijiren Technology, which shows
A retention time locked (RTL) method for the determination of trace level volatile organic compounds (VOCs) in environmental Aijiren Technology was developed on the Aijiren Headspace and GC/MS. Analysis on the GC/MS was performed in simultaneous Scan/SIM mode. This method can determine 66 VOCs over a calibration
