The only tunable diode laser (TDL) analyzer that measures H2S, CO2, and H2O using 1 Herriot Cell.
AccuLase-GPA™ was designed for specific natural gas and refinery applications. AccuLase is backed by 40 years of experience in the natural gas industry.
AccuLase-GPA™ uses a proprietary measurement cell that detects H2S down to 0.15 ppm, rivaling the capabilities of lead-acetate tape technology. AccuLase-GPA™ is specific to H2S without methane, CO2, or benzene interferences. Since AccuLase-GPA™ does not require a scrubber system, the response time is rapid. AccuLase-GPA™ can measure up to 4 streams.
Are you looking to avoid pipeline network “lock-out,” corrosion, or off-spec product? Do you need to automate custody transfer validation or better ensure contractual/regulatory compliance? Then AccuLase is the analyzer you need for operational certainty.

Frequently Asked Questions
What Makes AccuLase-GPA a More Accurate TDL H2S Analyzer than Lead-Acetate Tape?
AccuLase-GPA’s proprietary measurement cell detects H2S down to a 0.15 ppm lower detection limit, matching the sensitivity long associated with lead-acetate tape systems – but without the tape, chemicals, or replacement cycles those systems require. It’s also selective to H2S alone, so methane, CO2, and benzene in the sample stream don’t skew the reading, something tape-based methods can struggle with.
Why Choose a Tunable Diode Laser Analyzer over Scrubber-Based Systems?
Because AccuLase-GPA doesn’t rely on a background scrubber to isolate H2S, sample gas reaches the measurement cell faster, giving a quicker response to concentration changes. That directly reduces the risk of pipeline network lock-out, corrosion, and off-spec product reaching downstream customers – the core reasons operators move from scrubber-based instruments to a tunable diode laser platform in the first place.
How Many Streams Can this Tunable Diode Laser Gas Analyzer Monitor at Once?
A single AccuLase-GPA unit can monitor up to four gas streams, making it a practical, cost-effective option for custody transfer points or facilities running multiple pipelines without needing a dedicated analyzer for each one.
What Maintenance Does a TDL H2S Analyzer like AccuLase-GPA Require?
AccuLase-GPA runs with no consumables and automatic calibration, and it doesn’t need purge or instrument air to operate, so day-to-day upkeep is limited to periodic checks rather than scheduled tape or reagent replacement – a meaningful maintenance advantage over older H2S measurement technologies.
