Residual Gas Analysis is a general term for the analysis of gas and vapour species in vacuum chambers and vacuum processes. The Hiden RGA series quadrupole mass spectrometers provide for routine, fast, wide dynamic range residual gas analysis, measuring the partial pressures of the species that are critical to vacuum quality and process requirements. Applications include: vacuum chamber leak detection vacuum quality measurement and monitoring virtual leak detection outgassing studies bakeout...
Hiden gas analysis systems provide for high sensitivity, wide dynamic range, real-time analysis of almost any gas and vapour. Hiden’s application specific gas analysis systems are tailored to meet the specific application requirements, and include a range of special sampling, vacuum pumping and vacuum accessories. Hot zone sampling accessories are included for evolved gas analysis from furnaces, and thermo gravimetric analysers, TGA, for example. Thermal analysis methods are vital for catalysis characterization....
The analysis of volatile organic compounds at low concentration levels is fundamental to pollution monitoring and control. Hiden’s Hydramass spectrometer is a multi-stream gas analysis system for analysis of volatile organic compounds to the sub ppm level. In sea water the analysis of volatile organic compounds is used for both pollution monitoring and ecological studies. Hiden’s HPR 40 dissolved species analyser provides ppb sensitivity
Hiden's gas analysers provide for high sensitivity analysis of gases and vapours from gas production and storage facilities. Gas analysers provide for: Bottled gas quality assurance Diving gas monitoring Medical gas Semiconductor gas

In pilot plant and production scale fermentors, information relating to yield of product is of high importance. Hiden's gas analysers are configured with a multiport Off-Gas analysis manifold enabling simultaneous sampling from multiple fermentors. Data is used for the calculation of the respiratory quotient, carbon production rate and oxygen uptake rate. The Off-Gas measurement provides the respiratory quotient in a time and space averaged form and with good response time. By comparison data from multiple...
