Increasing Accuracy of Blood-Alcohol Analysis Using Automated Headspace-Gas Chromatography
Accuracy and precision are critical in blood-alcohol analysis because the toxicologist not only has to be confident in his or her results, but also must be prepared to withstand tough cross examination by defense attorneys. In addition, crime laboratories must comply with state regulations regarding blood-alcohol testing, including proficiencies which require the result to be within ±10%. The P...
متن کاملAtmospheric Analysis: Gas Chromatography
The determination of both naturally produced and anthropogenic organic species in the atmosphere is a key area in atmospheric chemistry research. Nearest to the earth’s surface, within the boundary layer of the troposphere, the determination of hydrocarbon species is important because of their ability to react rapidly with NOx in the presence of sunlight to form photochemical smog. At the other...

متن کاملPermanent Gas Analysis by Gas Chromatography – Vacuum Ultraviolet Spectroscopy
Gas Chromatography (GC) is a mature analytical technology used predominately for separating and quantifying the components of complex organic chemical mixtures. A wide range of columns and sample introduction techniques allow GC to be applied to most analytical problems involving volatile and semi-volatile compounds. One such application is the analysis of permanent gases, which are compounds t...
