Air separation units

Servomex has the solution for your ASU gas analysis needs

Accurate as analysis is essential for air separation unit (ASU) applications, improving process control, safety, and product quality. Our broad range of analytical solutions provide continuous, reliable analysis throughout the process.

A process that needs accurate gas analysis

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.

Monitoring a wide range of trace impurities

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.
