Incorporates PPC for enhanced ease-of-use, functionality and performance in an automated sample-tube handling system for unattended analysis of up to 50 samples. Concurrent desorption of the next sample while the current sample is undergoing GC analysis optimizes productivity. Also incorporates loading of internal standard into clean tubes to provide sample-integrity validation and to improve precision (repeatability) of the analysis.

Allows the ability to condition tubes during chromatography to minimize downtime and enhance productivity and also includes separate trap clean and test function, which saves time and protects the GC column and detector. Also incorporates the ability to re-collect sample for repeat analysis, the ability to perform dry purge without the internal standard accessory and the ability to perform tube and trap impedance measurement as a diagnostic of system performance. Provides truly outstanding analytical performance in an automated sample-tube handling system for unattended analysis of up to 50 samples.
