Lindy Miller, Agilent Technologies takes a look at achieving an inert gas chromatography flow path through better GC connections
Gas chromatography (GC) and GC/MS are powerful techniques for trace level analysis across a range of applications. Regulatory agencies are increasingly pushing for lower levels of detection of active compounds. At the same time, sample matrices are becoming more complex. Balancing these trends is a challenge for analysts who need to maximize sample throughput, while keeping systems within calibration. To avoid re-runs and improve productivity, analysts seek tools that help systems hold calibration, even after injection of samples with difficult matrices. An inert GC flowpath has been shown to extend the time and number of samples between calibration.
