US EPA Method 524.3 with the Teledyne Tekmar Atomx XYZ and the Thermo Scientific TRACE 1310 GC and ISQ LT MS System
US EPA Method 524.3 was used to determine the concentration of volatile organic compounds (VOCs) in drinking water matrices. For this study, a Teledyne Tekmar Atomx XYZ purge and trap (P&T) system and Thermo Scientific TRACE 1310 Gas Chromatograph (GC)/ISQ LT Mass Spectrometer (MS) was used to create a working linear regression (r²) calibration curve, method detection limits (MDLs), and minimum reporting level (MRL) confirmation for target compounds.
The Atomx XYZ is Teledyne Tekmar’s second-generation, multi-matrix P&T system and is based on the time-tested Atomx instrument platform. The concentrator’s efficient trap cooling design reduces sample cycle time by as much as 14% over the previous model. Combined with its 84-position soil and water autosampler, the result is more samples tested per 12-hour period. An innovative moisture control system (MCS) improves water vapor removal by as much as 60%, thereby reducing peak interference and increasing GC column lifespan. In addition to other refinements, the Atomx XYZ incorporates a precision machined valve manifold block to reduce potential leak sources and ensure the system is both reliable and robust. A reduced footprint of 13 cm (5”), compared to the previous generation, provides more bench space for laboratory tasks.
