The LaserGas™ II MP combines NEO Monitors’ tunable diode laser absorption spectroscopy (TDLAS) with a compact Herriott multi-pass cell to measure trace-level gases in a controlled extractive setup. By reflecting the laser beam multiple times between two spherical mirrors, it achieves a long optical path and ppb–ppm detection limits without increasing the analyzer footprint.
Built for stable, interference-free measurements, the LaserGas II MP has no moving parts, no consumables, and minimal drift. It delivers fast, reliable real-time data for gases such as H₂S, HCl, HCN, CO, CO₂, NH₃, O₂, and more. With ATEX/IECEx/UKEx and CSA Class I/Div 2 certifications, it performs well in corrosive, low-level, or high-purity applications where data quality is critical.
Typical applications include:
- Chemical and petrochemical processes
- Industrial gas purity checks (H₂ and specialty gases)
- Semiconductor gas monitoring
- H₂S emissions in pulp & paper, refining, and biogas plants
- Stack testing of corrosive gases in power applications
