Gas Chromatography

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 Air Products Gases are ideal for GC

Low Level of Total Hydrocarbon (THC) Impurities

Argon BIP® and Argon Premier ideally suited for ICP use.

Low Levels of Impurities, Moisture and Oxygen

Argon BIP® range, ideally suited for ICP-MS.

BIP® Technology Features In-Built Particle Filter

0.5 micron particle filter eliminates interfering particles containing metals from the gas.

Unrivalled Purity

Up to 300 times purer than conventional gases; Less than 10ppb O₂ and less than 20ppb H₂O

“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.
