| 21. | Gases in the cabin can be tested using gas chromatography, mass spectrometry and infra-red spectrophotometry.
|
| 22. | Analysis by gas chromatography ( GC ) is the method of choice for FAME analysis.
|
| 23. | The farm samples were tested by gas chromatography, the tests being run for several hours.
|
| 24. | In gas chromatography, the sample has to be volatilized at high temperatures, a tricky venture.
|
| 25. | Methods for detection in urine specimens usually involve gas chromatography-mass spectrometry or liquid chromatography-mass spectrometry.
|
| 26. | This is why they are used in gas chromatography, thin layer chromatography and affinity chromatography.
|
| 27. | Diallyl disulfide can be easily detected in the air or in the blood with gas chromatography.
|
| 28. | These included mass spectrometry and gas chromatography instruments.
|
| 29. | This step removes contaminant gases like hydrocarbons and halocarbons which can be removed by gas chromatography.
|
| 30. | The compound was isolated by preparative gas chromatography.
