Major Benefits of Laser Gas Detectors/TDLS Technology

Laser gas detection, based on Tunable Diode Laser Spectroscopy or TDLS, provides a solution to many challenges in environmental gas monitoring and process control. Axetris uses proprietary technology-enhanced TDLS for gas detection. A 0.05 nm narrow bandwidth diode laser beam is scanned across an absorption band of the target gas, thus performing a high-resolution near infrared absorption measurement.

The TDLS technology offers unique advantages, such as: precise optical, contactless measurements; excellent target gas selectivity; sub ppm-level detectivity for gases such as CH4, NH3, HCl, H2O and CO2; low cost of ownership; high stability, reliability and availability in the field (no regular replacements/calibration needed); long lifetime (10+ years).

The LGD is a cost effective solution for OEM integrators active in emission control and environmental monitoring. It allows for simple integration due to its self-contained and standalone system design. It also offers hot-gas measurements up to 220°C. The LGD covers further gas monitoring & detection applications in combustion control, greenhouse gas monitoring (CH4), safety and many more.
