Gas chromatography (GC) is a powerful analytical technique used to separate and identify volatile compounds in a sample mixture. One of the most widely used gas chromatographs is the HP 5890 A Series II by Hewlett-Packard. In this article, we will explore the features, benefits, and applications of this gas chromatograph.
Overview of Gas Chromatography
Gas chromatography is based on the principle of partitioning compounds between a stationary phase and a mobile phase. The stationary phase is typically a solid adsorbent or a liquid coated on a solid support, while the mobile phase is a carrier gas such as helium or nitrogen. The sample is injected into the chromatographic column, where the compounds are separated based on their affinity for the stationary phase and their volatility.
The HP 5890 A Series II gas chromatograph is a versatile instrument that offers high performance and reliability. It is equipped with a wide range of detectors, including flame ionization detector (FID), thermal conductivity detector (TCD), and electron capture detector (ECD), allowing for the analysis of various compounds.
