Gas Analyser GAN
Monitor gas composition, residual moisture and residual oxygen directly in the process – precise, traceable and documented. With automatic calibration, remote access, alarms and a Cloud Dashboard for continuous quality assurance.
Applications by industry
Make gas quality visible – continuous, documented, traceable.
The stationary and portable GASYCO analysers are equipped with high-precision sensors that deliver reliable and exact measurement results even under the most demanding conditions. They analyse the composition of gas mixtures as well as residual moisture and residual oxygen. Thanks to an integrated calibration function and automatically generated certificates, the accuracy of each sensor is verifiable at any time and traceable to a defined calibration gas.
The systems are housed in compact stainless steel enclosures and are ideal as on-site measuring instruments for long-term, continuous quality assurance. The portable version also has a pump, so samples can be taken from unpressurised systems as well; via the built-in flow controller the GAN can be connected in-line directly in the process. In every version the measurement is extractive: the GAN takes 0.5 ln/min from the gas stream.
Recipients for SMS and email alerts are easy to set up. The GAN reports immediately when the measured gas concentration is outside the defined tolerance ranges. Full functionality is also available remotely through any common web browser.
The integrated data logger continuously records all measured values – via USB, LAN or directly in the cloud solution with dashboard, export and access to all certificates and measurement reports. With Connect Enterprise the data can be integrated into your own systems via an API and OpenID sign-in.
Making gas quality visible
A gas mixture can be set, supplied or produced. What matters for quality-critical processes, however, is whether the actual gas composition stays within the defined limits at all times. The GAN monitors relevant gas parameters continuously, detects deviations early and documents measured values, alarms and calibrations automatically.
Your measurement task determines the sensors.
This is our standard. Not your limit.
The sensors, measuring ranges and operating data listed are our standard selection. For your measurement task we combine further sensors and measuring ranges – modularly, in the same device.

Where the device is used.
The right questions. The right answers.
Can I retrofit the GAN to an existing gas mixer?
Yes. The GAN monitors mechanical and digital gas mixers, in-line or in bypass; the existing mixer stays. This makes the actual gas composition visible at all times, including for shielding gases.
Does the GAN measure oxygen in the ppm range?
Yes: O₂ and CO₂ in ppm and percent, H₂ and He from 0 to 100 %, residual moisture from 0.1 ppm to 0.6 % (dew point -80 to 0 °C) and NO in ppm. We combine further sensors and measuring ranges modularly in the same device.
How is the GAN calibrated?
Automatically, including certificate generation. The accuracy of each sensor is traceable to a defined calibration gas; the certificates are available in the Gasyco Dashboard for any period.
Why measure continuously instead of taking spot checks?
Because deviations between two spot checks go undetected. The GAN monitors the gas parameters continuously, detects drift, moisture or contamination early and documents measured values, alarms and calibrations automatically – also in buffer tanks and pipework.
How is the GAN connected to the gas stream?
The GAN can be connected in-line in the supply line or in bypass. The measurement is extractive: in every version it takes 0.5 ln/min from the gas stream, because some sensors measure unpressurised. With the portable version, a downstream device can also be connected directly to the analyser’s process outlet; a variable area flow controller provides a defined flow for it. Inlet pressure 0.3 – 10 barg, connection via 6 mm compression fitting, push-in or quick coupling.
Stationary or portable – which version do I need?
The stationary GAN monitors one measuring point permanently. The portable version also has a pump, so it can take samples from unpressurised systems and measure at several measuring points in turn. Both are housed in compact stainless steel enclosures.
How does the GAN report deviations?
Immediately, as soon as a measured value leaves the defined tolerance: by SMS, email or relay contact. You set up the recipients yourself and assess limits to a standard or your own specification.
What is the GAN used for?
Wherever gas quality determines the process: shielding gas in welding, furnace atmospheres in heat treatment, protective gas for food packaging, process gases in pharma and biotech, and test gases in the lab. It measures gas composition, residual oxygen and residual moisture.
How are measured values and certificates stored?
The integrated data logger records all measured values continuously – via USB, LAN or directly in the Gasyco Dashboard with export and all certificates and measurement reports. With Connect Enterprise you integrate the data into your own systems via an API and OpenID sign-in.
Do I need a GAN if I already have a GAMI?
Usually not: the GAMI gas mixer is also available with integrated analysis, which is more economical and more compact. The GAN is the right choice for monitoring mechanical mixers or purchased mixtures, checking buffer tanks and pipework, or measuring at several points with the portable version.
