Tiger Optics LLC has introduced the LaserTrace-O2, a new module for its multispecies, multipoint and multigas analyzer. The instrument can detect many species, including H2O, CH4, H2, CO2, NH3 H2S and HF. The detection range extends down to 100 parts per trillion. Via fiber optic connections, the system provides remote monitoring of up to four analytes at four sample points for as many as four gases. It is wet-chemical-free and transportable and requires no calibration. The company says that it also is robust and low-maintenance.
