Gas Chromatography (GC) is one of the most common analytical techniques used today, during analysis chemical components of a sample mixture are separated in a column, and identified when they reach the detector to determine their presence or absence and how much is present.
The GC column is sensitive to so-called critical components, oxygen, moisture and hydrocarbons. It is therefore essential that the carrier gas, which assists the sample to travel through the column, is high purity and has absolutely minimal levels of these impurities.
Just some of the industries that utilise gas chromatography includes food and beverage, metals, pharmaceutical, geological, water and cement.
Why is gas purity critical for my analytical application?
Some impurities can damage analytical instruments and affect accuracy of results. Oxygen and moisture are critical impurities in many analytical techniques.
