CEMGAS 5000 H2 Laser Analyzer


The CEMGAS 5000 H2 Laser Analyzer utilizes patented cavity enhanced laser absorption spectroscopy technique OFCEAS and a patented low pressure sampling system.


The analyzer enables direct continuous measurements of low level of hydrogen regardless of the matrix for real-time monitoring and control of industrial processes.


Why choose the CEMGAS 5000 H2 Laser Analyzer?

In the recent past measuring H2 has been a challenge as most samples contain more than one non-H2 gas and isolating it under thermal conditions is difficult, laborious and prone to inaccuracies.

Fortunately AP2E has developed and deployed an innovative high resolution laser-based gas analyzer for rapid online measurement of low level of hydrogen in chlorine matrix or other gas with very high sensitivity, selectivity and accuracy.

The CEMGAS 5000 H2 Laser Analyzer is the first device in the world to be able to measure hydrogen in infrared by resonant cavity laser spectroscopy. The instrumentation enables quantitative monitoring with a Limit Of Detection (LOD) up to 3ppm.

Avoid the condensation phenomenon, the risk of chemical absorption/desorption and the cost of a heated sample gas line with the patented low-pressure sampling system for gas extraction and transportation.

The H2 Trace Laser Analyzer comes pre-calibrated for your application and with no optical moving parts it’s marked by a high MTBF of 5 years. The touch screen interface and on-board PC allows for local/remote control and real time display/recording of results.

What is H2 and why does it need to be measured?

H2 (hydrogen gas) is a diatomic molecule meaning that it consists of two atoms of the same element. It is the most abundant chemical substance in the universe. At standard temperatures, H2 is a highly combustible, colorless, odorless, tasteless, non-toxic gas. Highly flammable H2 will burn in air at a very wide range of concentrations between 4% and 75% by volume. Combined with other compounds, highly explosive reactions could be triggered by sparks, heat or just sunlight.

The necessity for monitoring this volatile gas is required as it poses a number of hazards to human safety, from potential detonations and fires to being an asphyxiant in its pure, oxygen-free form. As an example, depending on the concentration, a mixture of H2 and Cl2 (chlorine gas) can be flammable or explosive. For this reason hydrogen needs to be monitored continuously in order to keep the gas composition within the flammability limits.
