Performance of a next generation vial autosampler for the analysis of VOCs in water matrices

Abstract

In today's laboratories, increased efficiency and productivity are of extreme importance. Equally important is the ability to automate analyses without sacrificing sample integrity or data quality. A new vial autosampler has been developed to fully automate purge and trap analysis of water and wastewater samples in accordance with current EPA methods for volatile analysis. Research is presented demonstrating the autosampler's ability to transfer sample aliquots with the addition of internal standard or surrogate solutions. Data are evaluated for linearity, precision, and accuracy. In addition, the instrument's sample pathway is evaluated for carryover, inertness, and reliability.
