In this video, Diane Turner, director and senior consultant for Anthias Consulting Ltd., discusses her role in providing training and consultancy in gas chromatography (GC) and GC/MS. Turner outlines how she helps troubleshoot different labs' GC/MS approaches, breaking down their instrument set-up to ensure the samples are efficiently passing through the system and the separation and detection of analytes is optimized. Turner goes on to explain how comprehensive two-dimensional gas chromatography (GCxGC) can vastly improve sensitivity, easily analyzing complex samples and analytes with much lower detection limits.
