GCHS-MS Testing Lab
Choosing the appropriate GC-MS testing approach
A useful testing plan begins with the analytical question: which compounds need to be identified or measured, in which sample, and at what reporting level? Sample preparation and instrument conditions must be selected for that purpose. Headspace sampling may be suitable for some volatile compounds; direct or other introduction approaches may be appropriate for other applications. For an introduction to the technique, read about how GC-MS testing works
Sample submission checklist
Before sending a sample, provide its description, batch details, target analytes, specification and reporting requirements. Ask the laboratory to confirm sample quantity, container, storage conditions and transport instructions. These requirements can differ between matrices and tests.
What should a GC-MS report explain?
Depending on the agreed scope, a report may identify the method, sample, compounds investigated, results, units and relevant reporting limits. Where a result is below a reporting limit, interpret it against that limit rather than assuming the concentration is zero. For solvent-specific pharmaceutical requirements, review our pharmaceutical residual solvent testing page.
