Validation of USEPA Method 524.2 Using a Stratum PTC and the New AQUATek 100 Autosampler

Automation is the key to increasing laboratory productivity and minimizing costs. It is equally important to prove that the changes in technology to achieve these results may be done without sacrificing sample integrity or data quality. The AQUATek 100 is a new vial autosampler which features many new benefits to help increase productivity, minimize carryover, and provide more flexibility to the end user in terms of maintaining sample integrity and servicing the unit. The data presented in this application note was provided by a large drinking water facility and validates USEPA Method 524.21 with regard to reproducibility, Surrogate percent recovery, and Method Detection Limits (MDLs) using a Stratum Purge and Trap Concentrator (PTC) and the new AQUATek 100 Vial Autosampler interfaced to an Agilent 7890A GC and a 5975C Triple Axis Detector.
