GPR-7500 (A)IS Online H2S Analyzer
Online ppm hydrogen sulphide analyzer with electrochemical sensor, certified for flammable gas streams.

PPB-level trace nitrogen-in-argon/helium analysis without a gas chromatograph.
The LDetek LD8001+ is designed for ultra-pure argon or helium gas analysis, with an integrated ppb sub-system that makes low-ppb trace nitrogen measurement possible online, without needing a separate gas chromatograph. Its compact, maintenance-free 3U cabinet design suits both industrial and laboratory installations.
A unique Plasma Emission Detector, based on a duty-cycle-controlled system, measures trace nitrogen at ppb levels in high-purity argon or helium streams. Bypass sample-flow control maintains sample purity, and low sample consumption keeps operating costs down.
