Analysis and Quality Control

Analytical laboratories use gases to run their lab instruments. These gases must be very high or ultra high-purity gases to ensure accurate analyses and protect the instruments. Our extensive expertise providing premium specialty gases and services for analyses and quality controls allows us to meet these needs.

Analysis and Quality Control at a Glance

Analytical laboratories conduct analysis and quality controls on raw materials, end products and industrial emissions to detect the trace and quantity of different components and impurities.

Analytical gases used commonly to operate lab instruments and analysers include the following:

Pure gases such as helium, argon, nitrogen, hydrogen, air and oxygen, which are used as carrier gases to vehicle sample to detector. They need to be of very high purity so as not to affect the analytical results or the analytical equipment
Calibration gas mixtures, which contain from 2 to dozens components, with very precise dosages and high purity. They act as the reference gases used to calibrate the equipment itself
