The innovative technology from Archigas also enables the precise and fast measurement of helium in various background gases. Thanks to direct process integration at pressures of up to 200 bar, construction costs and emission losses of the valuable noble gas into the atmosphere can be effectively reduced – the solution is therefore also particularly suitable for helium recovery systems.

Archigas gas analyzers master every challenge in helium measurement!
1. Precision
The accuracy of the measuring devices available on the market hardly meet the high requirements of industrial applications. Parameters such as signal-to-noise ratio, hysteresis, temperature influence or reproducibility often do not meet customer expectations.
Compared to conventional thermal conductivity detectors (TCD), the Archigas solution offers significantly higher precision: when monitoring the helium purity, 100 ppm detection limit with a wide temperature range from -40°C to 90°C/125°C and almost 100% reproducibility is a decisive advantage
3. Cross sensitivity
In conventional gas analysis, changing flow rates and high pressures lead to undesirable cross-sensitivities. Complex and costly sample preparation is therefore required to ensure precise results.
Thanks to the innovative sensor technology, flow rate fluctuations have a negligible effect on the measuring accuracy. The devices provide stable and reliable measurement results even under varying conditions. Cross-sensitivities caused by pressure fluctuations can be detected by an external pressure measurement and compensated for reliably and reproducibly by means of cross-calculation.
2. Helium loss
A significant disadvantage of many conventional measurement methods is that helium is extracted from the process and then released into the atmosphere: The consequences are a waste of resources and considerable economic loss.
Due to the innovative screw-in design and the ability to operate even at high pressures, measurement is carried out directly in the process without helium being removed and released into the environment. This conserves resources, saves costs and makes the technology particularly efficient for helium recovery systems.
4. Calibration
The calibration of conventional devices usually requires a separate channel in which highpurity helium is used. Costly designs and considerable additional time are required, also because measurements are often taken at several points. Measurement efficiency and maintenance are impaired.
Calibration is performed directly in the process channel. As the chip is very stable, a zero-point calibration can be carried out automatically and simultaneously for all installed analyzers, if necessary, which considerably reduces the maintenance effort and lowers the operating costs. On request, calibration can also be carried out using substitute gas, which saves on the cost of expensive calibration gas.
