The portable 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.
