In many applications, gas analysis is part of a broader setup where multiple instruments operate together, data is collected continuously, and results support decisions and process control. 

The requirement is straightforward: gas analysis must remain stable when conditions are not, and this exactly the type of use GT7000 Tellus (released in May 2026) is designed for. That can mean vibration, limited space, changing process parameters, and the need to detect low concentration levels without drifting over long periods, whether the setup is used for confined space air monitoring in safety applications, research and pilot rigs, or industrial process monitoring.

Integration into measurement setups

When measurements must remain dependable despite vibration, changing process conditions, or long operating periods, the analyzer has to fit the system around it.

In practice, that means working alongside other instruments, following the same workflow, and delivering results that can be used without extra manual steps.

A rack-mounted, standalone format supports this kind of incorporation into multi-instrument measurement setups. It is a practical fit in areas such as process monitoring, emissions monitoring, and carbon capture, where gas analysis is not a one-time check but part of routine operation and repeated measurement cycles.

Analytical capability for complex gas mixtures

In many applications, gas composition is not fixed or fully known, and the same setup may need to handle changing concentrations and low concentration levels. The challenge is to keep the analysis usable when the gas matrix varies, and not every component can be defined in advance.

FTIR-based gas analysis supports simultaneous measurement of multiple gases from a single sample and can also support identification of unknown components.

It supports both continuous measurements and in-situ analysis, enabling simultaneous identification and quantification of multiple gases across the infrared spectrum.

Typical gases in fixed system applications

Depending on the application, gases commonly measured can include CO₂, CO, SO₂, NOₓ, HCl, HF, NH₃, N₂O, CH₄, H₂O, and various VOCs. In emissions monitoring, regulatory reporting often requires accurate measurement of several of these simultaneously. In carbon capture and CO₂ purity monitoring, trace impurities at low concentration levels matter. In combustion research, the composition of exhaust gases changes dynamically and needs to be tracked across the full measurement cycle.

Terra, Mobilis, Tellus: the same FTIR core in different setups

Gasmet’s product family uses the same FTIR measurement approach across different ways of working, from mobile field use to fixed measurement systems. Gasmet’s FTIR analyzers can measure up to 50 and quantify over 500 gases simultaneously from a single sample, without hardware changes between compounds.

GT5000 Terra is a portable and splashproof multi-gas FTIR analyzer, that can measure up to 50 gases simultaneously from ambient air, making it possible for you to detect the unexpected. The GT6000 Mobilis is EN15267-4 QAL1 certified (MCERTS) portable FTIR analyzer for monitoring gas concentrations in hot, wet, and corrosive gas streams.

GT7000 Tellus applies the same technology core in rack-mounted, standalone form for fixed setups, where gas analysis is one part of a larger measurement system. This supports workflows where measurements are continuous or repeated, and where stability on varying process conditions is a practical requirement.
