Tunable diode laser (TDL) and distributed feedback (DFB) laser: Leading-edge solutions

Tunable diode laser (TDL) absorption spectroscopy is broadly used for emission control of air contaminants including ammonia (NH3), hydrogen chloride (HCl), hydrogen fluoride (HF), carbon dioxide (CO2) and carbon monoxide (CO) as indicators of anthropogenic and natural sources.

Among the impressive features of our TDL analyzer are its fast response time, direct absorption technique and sensitive detection (ppm to ppb). Along with its ease of use (i.e. no skilled operator needed), it provides a high selectivity of gases and impurities and requires virtually no recalibration. What’s more, our TDL analyzer is insensitive to harsh conditions, is compact, portable and robust, and comes with low operating costs. All of these value-added functionalities make it very popular solution for numerous industries.

In addition, CI Analytics has developed a new laser analyzer capable of detecting and quantifying trace gases and impurities at ppm and ppb levels. Thanks to its high precision and accuracy, this distributed feedback (DFB) laser provides results in seconds.

Featuring a wide tuning range and narrow line-width, this laser-based analyzer is ideal for high sensitivity selectivity methods. Moreover, the laser diode provides a stable operation point by thermoelectrical controls and over 1 million hours of available analysis.

This new laser technology provides the best combination of compact size, low power consumption, high speed, high sensitivity as well as high precision of measurements. It is reliable for use in hostile environments and for applications requiring trace gas analysis including field measurements, environmental and emission monitoring. The instrument requires minimal sample preparation, is drift-free and the intervals for recalibration are far apart.
