A gas chromatograph (GC) is an analytical instrument that measures the content of various components in a sample. The analysis performed by a gas chromatograph is called gas chromatography. Principle of gas chromatography: The sample solution injected into the instrument enters a gas stream which transports the sample into a separation tube
Volatile Organic Compounds (VOC) in Air. Many substances harmful to human health are detected in atmospheric air. Even substances that are not at a concentration level that has a direct effect on human health may cause concerns of carcinogenicity after long-term exposure. This shows an example of the gas chromatograph-mass spectrometer (GC/MS
Ultra-Fast Analysis of Volatile Organic Compounds in Water By Headspace-GC/MS/MS LAAN-A-MS-E033 Volatile organic compounds (VOCs) in environmental water and tap water are typically analyzed by headspace-GC/MS or by purge-and-trap-GC/MS. Because many of these VOCs exhibit low solubility in water and vaporize easily, analyses must be conducted
analysis of Volatile Organic Compounds (VOCs) in drinking water. Currently, the majority of environmental laboratories analyzing these compounds in drinking water for compliance purposes, use either method 524.2 or 524.3. One of the challenges faced by laboratories performing this analysis is the lack of robustness and stability of BFB

VOC measurements are commonly performed using a thermal desorption-gas chromatograph mass spectrometer (TD-GC/MS). To reduce the risk of analysis failures due to the time-consuming process of sampling the atmosphere, multiple tubes are typically used for backup sampling or samples are re-analyzed using a TD restore function.
