Description
Agilent 8890 RGA GC System – Refinery Gas Analyzer with Dual TCD, FID & Multi-Valve Configuration
Agilent 8890 RGA GC System – Refinery Gas Analyzer with Dual TCD, FID & Multi-Valve Configuration is a fully configured gas chromatography platform designed for refinery gas and light hydrocarbon analysis. This system utilizes a multi-valve architecture with integrated TCD and FID detectors to enable comprehensive analysis of permanent gases and hydrocarbon components in a single run.
The system is optimized for separation and quantification of hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, and light hydrocarbons including methane through C6+ fractions. Multiple switching valves and column sets allow precise flow path control, including heart-cutting and backflush techniques to improve resolution and reduce analysis time.
Dual thermal conductivity detectors (TCD) provide accurate measurement of permanent gases, while the flame ionization detector (FID) delivers sensitive quantification of hydrocarbons. The integration of molecular sieve and PLOT-style column configurations enables efficient separation of complex gas mixtures.
This configuration is commonly used for refinery process monitoring, gas plant analysis, and petrochemical quality control, where reliable and repeatable measurement of gas composition is critical.
This refurbished Agilent 8890 GC Refinery Gas Analyzer System has been fully tested and verified to be in proper working condition by Alliant Scientific.
