TDL H2S, CO2, H2O Analyzer
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.

Panel-Mounted Pressure Regulation and Filtration Ensure Sample Meets Analyzer Requirements
No Laser Damage if H2O or Glycol Gets Passed Filter. Worst Case is Lost Sensitivity From Mirror Contamination Which Can Be Rectified With Cleaning Using Methanol.
If Gas / Liquid Penetrates Laser Chamber, Gas Exits Vent Line and Condensables Settle at Bottom of Cell.
Diagnostic Alarm Indicates Over-Range Invalid Readings.
Includes a Proprietary Herriot Cell and On-Board Pump For Maximum Sensitivity
Vacuum Pump Reduces Cell Pressure to Below Atmospheric to Minimize Cross Interferences (CO2, Methane)
Pump Allows AccuLase to Directly Measure H2S Without Using a Scrubber (Indirect Subtraction Method).
