All samples heated in the gas chromatograph -mass spectrometer ( GCMS ) gave off water. 4. One way is to measured with gas chromatograph -mass spectrometers. 5. The sample is then admitted to a gas chromatograph . 6. Cadwallader and his team used a gas chromatograph . 7. A gas chromatograph can be used to determine the amounts of the methyl boranes in a mixture. 8. The gases extracted from the sample oil are injected into a gas chromatograph where the columns separate gases. 9. The CIR features a 100-litre combustion chamber surrounded by optical equipment and diagnostic packages, including a gas chromatograph . 10.
