Fixed Gas Purity Monitoring Systems (GPMS)
Gas Purity Monitoring System (GPMS) is a fixed analytical system capable of analyzing trace oxygen and moisture in high purity hydrogen, nitrogen, helium, and argon bulk gases and traces moisture in oxygen and carbon dioxide. The system utilize a series of cavity ring down spectrometers. Each spectrometer communicates with an on-board PLC for outbound communication with the customers FMS.
We offer a four different options, depending on the combination of gases you need tested.
Mobile Gas Analytical Systems (Analytical Carts)
Our carts are mobile, self-contained systems used for the continuous measurement of trace O2 and H2O gas impurities to the part-per-billion level in UHP gases.
Continuous Quality Control (CQC) Gas Monitoring Systems
A continuous quality control gas monitoring system is a real-time, automated setup used to monitor and ensure the quality of gases in various industrial and environmental applications. It consists of sensors and instruments that continuously analyze and report the composition, purity, and various parameters of gases within a specific process or environment. This system provides ongoing data and alerts, allowing operators to maintain consistent gas quality, identify deviations, and take immediate corrective actions if necessary.
Air Separation Unit (ASU)
An air separation unit (ASU) is an industrial facility designed to separate and produce high-purity gases, such as oxygen, nitrogen, and argon, from atmospheric air. It operates through a process called cryogenic distillation, which relies on the differences in boiling points of various gases. In an ASU, ambient air is compressed and cooled, leading to the liquefaction of air components. These liquefied gases are then separated and purified by distillation at extremely low temperatures.
