Automated Dilution of Samples Using US EPA Method 8260 on the Teledyne Tekmar Atomx XYZ and Thermo Scientific TRACE 1310 GC and ISQ 7000 MS with an Advanced Electron Ionization (AEI) Source
Abstract
The Teledyne Tekmar Atomx XYZ purge and trap (P&T) system performed the automated dilution of high-level volatile organic compound (VOCs) water samples using US EPA Method 8260. Determination was performed by a Thermo Scientific TRACE 1310 Gas Chromatograph (GC) and ISQ 7000 Mass Spectrometer (MS) with Advanced Electron Ionization (AEI) Source. A working linear calibration curve for target compounds was created and accuracy and precision of the Atomx XYZ’s automated dilution function was evaluated.
Introduction
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%, 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 reliable and robust.
