Requirements of an Automated Sample Delivery System in Today’s Realm of Ever Increasing Sensitivity Demands Utilizing the Atomx Concentrator/Multimatrix Autosampler
As today’s instrumentation and experimental techniques improve on sensitivity and efficiency, we must also provide better ways to decrease carryover and ensure the instrumentation is running at its optimum capability. In this study, data was collected to evaluate carryover of target analytes in subsequent blanks following high concentration samples. The sample analysis was automated using the Atomx, Teledyne Tekmar’s new robotic autosampler in combination with a Purge and Trap (P&T) concentrator. The Atomx was interfaced to a Gas Chromatograph/Mass Spectrometer (GC/MS) system for quantitative analysis. This investigation will consider the effectiveness of different rinse solutions, temperatures, volumes, and frequency.
