From theCambridge English Corpus Known amounts of the gas (as measured bygaschromatography, see below) were injected into the flasks through the rubber caps with a syringe. From theCambridge English Corpus Periodically, gas samples were collected and analysed viagaschromatography. From theCambridge English Corpus It was perhaps surprising that no one from the workshop had yet tried truly field-portablegaschromatographyequipment. From theCambridge English Corpus Gaschromatographywas employed for the initial optimization of the extraction, purification and analysis of the mosquito cuticular hydrocarbons and for their quantitative analysis.
