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.

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.

A cryogenic purifier is a device or system designed to separate and purify gases through the use of extremely low temperatures. It utilizes the principles of cryogenics, which involve the cooling of gases to very cold temperatures, often near or below their boiling points. By cooling gases to such low temperatures, impurities and unwanted components can be condensed and separated from the desired gases, allowing for the production of high-purity gases for various industrial and scientific applications.

ASTG offers an extensive line of fixed gas analytical systems. These systems can be used for spot-checking manufacturing issues to “battery-limit” testing entire facilities. Our systems are designed using Ultra-High Purity Engineering Techniques.

The flagship gas management system, ASTG can automate your UHP gas analytical systems in the smallest footprint possible in orbitally welded components. Utilizing gas-actuated stainless steel diaphragm valves, manifolds can asynchronously port multiple samples, calibration gases and zero gases throughout your analytical system without fear of cross contamination or leakage. High speed activation legs are included on all systems to insure the fastest, most representative sample possible. This will ensure process and quality control when it’s most critical.

Depending on the blend tolerance requirements ASTG offers a range of options to meet the needs of the application. From systems designed with fixed orifices to actively managed mass flow controllers and the addition of active analysis on the product stream to adjust the blend mass flow controllers continuously to maintain the blend ratio as the instantaneous flow demand varies, ASTG has the level of expertise required.

This unit is designed to use clean, dry air as an oxidizing gas. The amount and proportion of the gas may be adjusted to maximize converter efficiency. Air should be run at a state of excess relative to the total sulfur content to prevent a limited reaction.
