The LaserTrace™ delivers an outstanding value, with the most competitive balance of price and performance. It offers many advantages, including:

Absolute technology. Based on measurement of light absorption in accordance with Beer's Law, CRDS provides a highly accurate and reliable quantification with no need for costly, time-consuming calibration.

Parts per trillion (ppt) to parts per million (ppm) detection range. Wide dynamic range is achieved through automatic selection of appropriate spectral lines, with no need for calibration. Much longer pathlengths (~30 km) than traditional multipass cells (10-100 m) enable ultra-low detection capabilities of 200 ppt without vacuum pumps.

Instant response. Optimal real-time analysis capability on up to four samples simultaneously.

Measurement in corrosives. A non-contact measurement technique, CRDS makes trace gas measurement in corrosives possible. The LaserTrace™'s robust design makes it a reality.

High selectivity. Based on absorption spectroscopy, CRDS attunes to the unique molecular "fingerprint" of the specific species. This selectivity eliminates the background effects of other species found in the matrix gas.
