Headspace Gas Chromatography
Headspace technology, Headspace gas chromatography uses Headspace technology, headspace gas—from the top or "head" of a sealed container containing a liquid or solid brought to equilibrium—injected directly onto a gas chromatography, gas chromatographic column for separation and analysis. In this process, only the most Volatility (chemistry), volatile (most readily existing as a vapor) substances make it to the column. The technique is commonly applied to the analysis of polymers, food and beverages, Blood alcohol content, blood alcohol levels, Environmental monitoring, environmental variables, cosmetics, and Pharmaceutical industry, pharmaceutical ingredients. Volatiles Materials that exist primarily in the gas phase at STP (i.e., "evaporates more than 95% by weight within six months under ambient evaporation testing conditions") are referred to as "volatile." Many natural and man-made (Anthropogenic hazard, anthropogenic) materials are stable in two states at STP, earning them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
