US EPA Method 524.3 - Atomx XYZ and Agilent 7890B GC/5977A MS
US EPA Method 524.3 was used to determine the concentration of volatile organic compounds (VOCs) in drinking water matrices. The Teledyne Tekmar Atomx XYZ purge and trap (P&T) system along with an Agilent 7890B Gas Chromatograph (GC)/5977A 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 most advanced 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.
