Improved Determination of Volatile Organic Compounds in Water by SPME and GC/MS: ISO Standard 17943
The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables low limits of detection and easy automation of the whole method. ...

Meeting the Korean Method ES 04603.2b for 12 VOC with Static and Dynamic Headspace GC/MS
Introduction The Korean Standard Method for Drinking Water ES 04603.2b requires static headspace with GC/MS to monitor 12 Volatile Organic Compounds (VOCs). The Minimum Quantitation Limit (MQL) must be less than 5 ppb. The method requires the calibration curve to have a correlation coefficient greater than 0.98 or a Relative Standard Deviation (RSD) of the Response factors (Rf) less than 25%. ...

US EPA Method 8260 with the Tekmar Lumin P&T Concentrator and Thermo Scientific TRACE 1310 GC and ISQ MS
Abstract US EPA Method 8260 is used primarily by environmental labs for the analysis of volatile organic compounds (VOCs) in soils and water. While this method is effective at concentrating the trace levels of VOCs sometimes found in water and wet soils, it also tends to transfer significant quantities of water vapor to gas chromatographymass spectrometry instruments (GC-MS). To reduce the ...
