The ASU separates atmospheric air into three pure gaseous elements – nitrogen, oxygen and argon. Further separation is required for quantities of noble gases such as neon, krypton and argon. Accurate gas compositional analysis is essential to ensure purity across the air separation process.
Maintenance of product purity is essential between the separation process and product transportation by pipeline or vehicle. This requires highly accurate trace measurements for a range of impurities to ensure that quality is maintained at the highest possible standards.
