Gas chromatography (GC) and ion chromatography (IC) are two analytical techniques used to separate and identify chemical compounds. GC is used to separate volatile compounds, while IC is used to separate ionic compounds. Both techniques use a mobile phase to carry the sample through a stationary phase. The mobile phase is typically a gas for GC and a liquid for IC. The stationary phase is typically a solid for GC and a resin for IC.
GC and IC are important analytical techniques because they can be used to identify and quantify a wide variety of compounds. GC is often used to analyze environmental samples, such as air and water. IC is often used to analyze food and beverage samples. Both techniques can also be used to analyze biological samples, such as blood and urine.
