Dual laser gas analyser

September 2011 Analytical Instrumentation & Environmental Monitoring

With the introduction of the Model 5100HD gas analyser with a dual laser platform, Ametek has expanded its line of Model 5100 Series gas analysers based on tunable diode laser absorption spectroscopy (TDLAS). Two separate lasers are installed in the instrument and share a common optical path through the sample. This allows the instrument to measure two analytes simultaneously, resulting in significant cost savings for users.

The Model 5100HD is capable of dual stream analysis and can measure any two combinations of water vapour, methane, hydrogen sulphide, carbon dioxide and oxygen in process or flue gas. Sealed reference cells containing known amounts of analyte gases allow referencing of the emission wavelengths of the lasers. As a result users can line lock the lasers and continuously verify the instrument’s calibration.

The Model 5100HD is designed to handle sample gases with high dew points. In the standard version the sample cell can be heated to a maximum of 100°C. A version is also available for 150°C. The instrument is set up to perform digital implementation of wavelength modulation spectroscopy (WMS). It employs digital signal processing methods that allow multivariate calibration for accurate measurement of two separate species with completely overlapped spectral responses.
