Class I Div 1 Groups B, C, D T5; Zone 1 Ex d [ia] IIB+H2 T5 (D1 model)

Overview

AccuLase-GPA is a TDLAS process analyzer that measures H2S, CO2 and H2O in gas-phase samples, including natural gas and refinery applications, with all three analytes measured in about 30 seconds. An on-board vacuum pump keeps the Herriott cell at partial vacuum so H2S is measured directly without a scrubber consumable. The D1 model is certified for Class I, Division 1 / Zone 1 locations.

Working Principle

A near-infrared laser is tuned to the absorption wavelengths of each analyte. A 52.6 cm Herriott cell with 100 laser passes gives a 52.6 m optical path for maximum sensitivity, and the on-board vacuum pump improves separation from interferences.

Applications

Benefits

Low maintenance — simple sample system, quarterly PM
Rapid multi-parameter results for process control and custody transfer
Small footprint
