Introduction
The TurboMatrix™ 650 ATD is the most sophisticated of the PerkinElmer® family of five Thermal Desorber models. It incorporates technology, allowing a portion of desorbed sample vapor to be re-collected rather than injected into the gas chromatograph, providing a second sample. This sample, which would otherwise be lost through sample splitting, can now be re-collected onto the original or a fresh sorbent tube to enable a subsequent analysis.
This functionality is useful in situations where the sample contains both high-level and lowlevel concentrations of analytes. In such cases, the ability to recollect sample allows the sample analysis to be repeated using a different split ratio.
Another key benefit of sample re-collection on the original or different tubes is that analysis can be repeated by an independent laboratory for audit or litigation reasons.
Furthermore, automatic re-analysis is possible because the re-collected sample is on the same magazine. This approach also minimizes the cost of both labor and the requirement for a second autosampler magazine with additional tubes to make the re-collection.
