Ametek 5100HD TDLAS

The Ametek 5100HD TDLAS Gas Analyzer is based on Tunable Diode Laser Absorption Spectroscopy (TDLAS). The dual laser gas analyzer Ametek 5100HD TDLAS hosts a dual laser platform. Two separate lasers are installed in the instrument, sharing a common optical path through the sample, enabling the measurement of two analytes simultaneously. This results in significant cost savings to our customers. Where the required concentrations of the analytes differ considerably such that different path lengths are required, two sample cells are used. Ametek 5100HD TDLAS is also capable of dual stream analysis.  The dual laser Ametek 5100HD TDLAS measures water vapor, methane, hydrogen sulfide, carbon dioxide, and oxygen in process or flue gas.

Ametek 5100HD TDLAS is designed to handle sample gases with high dew points. The standard version has its sample cell heated to a maximum of 100°C. A version is also available for 150°C.

A key feature of the dual laser gas analyzer Ametek 5100HD TDLAS is the use of sealed reference cells, which contain known amounts of analyte gases measured, for referencing the emission wavelengths of the lasers.  The use of reference cells enables both the ability to line-lock the lasers and to continuously verify the instrument calibration.

Dual laser gas analyzer: Ametek 5100HD TDLAS PDF


Tunable Diode Laser Absorption Spectroscopy (TDLAS) has become an accepted technology for crucial on-line gas analysis applications. The high reliability of the solid state lasers used in TDLAS instruments is the result of decades of technology development for the Telecom industry. Correspondingly, TDLAS-based instruments tend to be very robust, reliable and require minimal maintenance.

Three key measurement attributes of the TDLAS technique are: specificity for the analyte, high sensitivity, and fast response speed. The specificity of TDLAS is the result of the extremely high spectral resolution achievable.
Emission bandwidths for tunable diode lasers are very narrow, which results in the ability to isolate a unique absorption line of an analyte species. A second advantage of TDLAS is the ability to rapidly tune the lasers, so techniques like wavelength modulation spectroscopy (WMS), which yield dramatic sensitivity enhancements over a direct absorption approach, are easily implemented. Because TDLAS is an optical technique, it also offers a very fast response speed. The high specificity, sensitivity, and response speed of TDLs in the Ametek 5100HD TDLAS make them very suitable for a variety of process measurements.
