Portable analyzer based on tunable diode laser absorption spectroscopy
analyzer provides superior analyte specificity, sensitivity and measurement
speed of response. The initial version of the analyzer is configured for the
measurement of H2O in natural gas, bulk gases and hydrocarbon gas streams. Additional
analytes will include O2, CO2, CO and CH4. The hand-held, battery-powered device
provides approximately 8-hours of use before requiring a recharge. Other features
include compact, fully-enclosed optics, sample handling, on-board reference
cell for laser line lock, and all digital signal processing. Its laser module
has an internal Thermal Electric Cooler (TEC) and thermistor for laser
wavelength stability. Application-specific gas cells with a wide range of path
lengths are available.
Each unit is factory
calibrated. The laser wavelength stability and non-contact nature of the
measurement eliminate the need for field adjustments.
