CEMGAS 5000 CH4 Laser Analyzer


The CEMGAS 5000 CH4 Laser Analyzer is your cost effective solution to meeting the new EPA's methane regulatory compliance requirements.


The analyzer is a complete pre-calibrated laser infrared spectrometer for the measurement of low level CH4 in combustion process and pure gas. It's patented Optical Feedback Cavity Enhanced Absorption Spectroscopy (OFCEAS) IR technology allows for enhanced specificity, selectivity, accuracy and stability.


Why choose the CEMGAS 5000 CH4 Laser Analyzer?

This CH4 Laser Analyzer is pre-calibrated for your application and the OFCEAS IR technology associated with low-pressure sampling provides exceptional selectivity, enabling simultaneous multi-component measurements without interferences, regardless of the matrix.

Its patented low-pressure sampling system allows for low-cost installation and low flow rates (3-9 L/h) without degrading response time; accumulation of contaminants lines and filters is greatly reduced.

Containing no optical moving parts this methane analyzer was built strictly for industrial and on-board mobile applications. It includes a touch screen interface and on-board PC for both local and remote control, allowing for off site measurements. The interface also features real time display/recording of results.

With response times less than 2 seconds and zero drift the CEMGAS 5000 CH4 Laser Analyzer a complete, reliable, robust, low-cost and easy-to-use solution for the low level CH4 analysis in combustion process and pure gas.

What is CH4 and why does it need to be measured?

Commonly known as Methane, CH4 is a colorless, odorless and flammable hydrocarbon gas that is the chief constituent of natural gas. According to the EPA, it is the second most prevalent greenhouse gas emitted in the US from human activities and globally it accounts for over 60% of emissions from the same source.

On it's own methane gas is non-toxic but can cause death by asphyxiation due to the fact that it can displace oxygen. When mixed with other substances it does have the potential to become poisonous and since it is the main component in natural gas, the potential exists for this to occur anywhere it is used. Methane is also highly explosive and can be deadly when ignited.

Recently the EPA issued three final rules that collectively update the New Source Performance Standards (NSPS) and are designed to reduce methane, volatile organic compounds (VOC) and toxic air pollutants. In order to meet these regulatory compliance requirements companies must use equipment that meets the specifications and performance criteria in EPA Method 21. The CH4 laser analyzer offers an innovative and cost effective solution for these new regulations.
