Laser Gas Detection Modules

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

Axetris' Laser Gas Detection (LGD) Modules are self-contained, ready-to-use devices for the measurement of gases such as NH3, (H2O), HCl, (H2O), CH4, CO2. 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.

Continuous Gas Detection

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 precision with high target gas selectivity, calibration-free operation, low-cost-of-ownership and easy OEM integration.
