A gas analyzer is used to determine the concentration of target gases within a mixed atmosphere. In many settings its primary role is safety (alerting when levels become too high or too low), but it is equally valuable for improving efficiency, product quality, and process understanding. Modern gas analysis increasingly relies on real-time, multi-species measurement, because many processes do not behave neatly at steady state.
Green Hydrogen
Green hydrogen production and utilisation place strong demands on analytical confidence because impurities and composition drift can affect downstream processes and performance. Hiden gas analysers can be used to track hydrogen-containing mixtures over time, verify gas purity during production and clean-up, and monitor breakthrough behaviour during purification and storage studies - particularly where transients (start-up, switching, load change) matter.
Carbon Capture
In carbon capture, gas analysis is not only about measuring carbon dioxide; it’s about understanding capture performance and the factors that influence it. Hiden gas analyzers can be used to characterise inlet/outlet composition, quantify slip and conversion behaviour, and monitor impurities/by-products that affect capture media and process stability - supporting both optimisation and longer-term performance trending.
Fermentation and Bioreactor Monitoring
Bioprocessing often comes down to gas uptake and gas evolution rates, because these link directly to metabolism, yield, and process state. Hiden gas analyzers can be used to provide real-time off-gas measurement of key species (commonly oxygen and carbon dioxide in aerobic processes, and hydrogen and methane in anaerobic processes), enabling calculation of respiratory metrics and early detection of drift during development and scale-up.
Gas Production and Storage
Gas production and storage facilities need dependable analysis of gases and vapours for quality assurance and safety. Hiden gas analyzers can be used for routine composition checks, monitoring changes during handling, storage, and transfer, and identifying contamination or outgassing issues that may only appear as gradual baseline drift over time.
Gas Separation Studies
For separation technologies, the key question is performance: what enters, what exits, and how that changes during switching, regeneration, or breakthrough events. Hiden gas analyzers can be used to measure inlet/outlet (or feed/permeate) compositions continuously, quantify separation efficiency in real time, and capture transient behaviour that would be missed by slower or single-species methods.
Glovebox Monitoring
Gloveboxes depend on stable, controlled atmospheres, where leaks, contamination and outgassing can quickly undermine sensitive work. Hiden gas analysers can be used for measurement and monitoring of glovebox environments, supporting long-term trending, alarm thresholds, and rapid identification of excursions during routine operation.
High Purity Gas Analysis
High purity applications require reliable detection of low-level contamination and strong repeatability. Hiden gas analysers can be used for industrial and research purity verification, monitoring trace impurities and providing baseline trending to flag gradual changes that can affect processes long before a failure becomes obvious.
Human Breath Analysis
Breath research depends on non-invasive sampling and the ability to resolve low-concentration compounds as they change rapidly. Hiden gas analysers can be used for real-time studies of low concentration breath compounds, enabling breath-by-breath monitoring and time-resolved measurement approaches used in medical and physiological research.
Clean Combustion Research
Combustion research increasingly focuses on improving efficiency while minimising emissions, and that requires time-resolved visibility of evolving gas chemistry. Hiden gas analysers can be used to provide real-time insight into combustion dynamics, supporting studies across engine efficiency, industrial combustion optimisation, alternative fuels, and emissions behavior during changing operating conditions.
