US EPA Method 524.2 - Atomx XYZ and Agilent 7890B GC/5977A MS
US EPA Method 8260, in conjunction with Methods 5030 and 5035, was used to determine the concentration of volatile organic compounds (VOCs) in water and soil matrices. The Teledyne Tekmar Atomx XYZ purge and trap (P&T) system along with a Thermo Scientific TRACE 1310 Gas Chromatograph (GC) and ISQ Single Quadrupole Mass Spectrometer (MS) was used to create a working linear calibration curve and method detection limits (MDLs) 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 life span. 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.
