Model 5100 Series Gas Analyzer
Based on Tunable Diode Laser Absorption Spectroscopy (TDLAS)
Introduction
Over the past years, near Infrared 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.
t 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
