Laser Gas Detection
Modules for OEM Integration
Laser Gas Detection (LGD), based on Tunable Diode Laser Spectrometry (TDLS), provides a solution to many gas detection challenges in emission monitoring and process control. The technology offers unique advantages like precise optical, contact-less measurements, excellent target gas selectivity and sub ppm-level detectivity.
Axetris uses proprietary technology-enhanced TDLS for gas detection, where a 0.1 nm narrow bandwidth diode laser beam is scanned across an absorption band of the target gas, performing a high-resolution near-infrared absorption measurement. Electronic lock-in technology allows separating the gas absorption information from electro-optical system information, leading to a detection method eliminating the need for a physical reference channel and offering continuous sensor status monitoring. Axetris' LGDs thus present a clear alternative to current sub-optimal detection solutions and combine precise with high target gas selectivity, calibration-free operation, low-cost-of-ownership and easy OEM integration.
