Application 192-00
Agilent Natural Gas Analyzer
Technical Overview
Application Highlights
• A Thermal Conductivity Detector (TCD) is used to identify isobutane, n-butane, isopentane, n-pentane, carbon
dioxide, ethane, hydrogen sulfide, propane, oxygen/
argon composite, nitrogen, methane, and carbon
monoxide with an initial C6+ composite backflush to
detector.
• The lower detection limit on the TCD is 200 ppm for all
components except carbon monoxide, which is 400 ppm.
• System compliant with Gas Processors Association
Methods 2177 and/or 2261.
• Analysis time is approximately 25 minutes.
Optional Configurations
