The aim of this application note is to report the analytical performance of static headspace (HS) and solid phase microextraction with Arrow technology (SPME Arrow) sampling techniques for the determination of benzene, toluene, ethylbenzene and xylenes (BTEX), chlorinated and brominated volatile organic compounds (VOCs) in drinking water by using a Thermo Scientific™ TSQ™ 9000 triple quadrupole GC-MS/MS system.
To demonstrate the compliance of the Teledyne Tekmar Atomx XYZ purge and trap (P&T) system for online extraction and analysis of volatile organic compounds (VOCs) in soil with the Thermo Scientific™ ISQ™ 7610 single quadrupole mass spectrometer. Separation of targeted VOCs was achieved using the Thermo Scientific™ TRACE™1610 gas chromatograph (GC). Linearity, detection limit, precision, and accuracy were assessed to evaluate method performance in accordance with Chinese Method HJ 605.
This application demonstrates a routine analytical method that meets the requirements outlined in U.S. EPA Method 524.2 for the quantitation of volatile organic compounds in drinking water, using the Teledyne Tekmar Atomx XYZ purge and trap (P&T) system along with a Thermo Scientific™ ISQ™ 7610 MS system coupled with a Thermo Scientific™ TRACE™ 1610 Gas Chromatograph (GC) and Thermo Scientific™ Chromeleon™ Chromatography Data System (CDS). Method linearity, method detection limit (MDL), precision, and accuracy were assessed to evaluate method performance.
This technical note describes two of the mentioned strategies to overcome or reduce the SSE, namely the Strong Solvent Loop (SSL) and CIPs. Both approaches can deliver satisfying chromatographic results with limited effort or system adaptation. The SSE is shown and discussed at five injection levels, and the mitigation of SSE by implementing SSL and CIPs is evaluated for two column dimensions and three different sample solvents.
Demonstration of an analytical method that meets the requirements outlined in U.S. EPA Method 8260D utilizing U.S. EPA Methods 5030 and 5035 preparation methods for the quantitation of purgeable organic compounds (POCs) in wastewater and soil. Method linearity, method detection limit (MDL), and Initial Demonstration of Capability (IDC) were assessed to evaluate method performance.
