Design Requirements for GC System with TCD and FID for Light Hydrocarbons Analysis
A self-funded project requires a gas-chromatography system with Thermal Conductivity Detector and Flame Ionization Detector for analyzing light hydrocarbons. The project seeks an end-to-end design that includes column selection, carrier gas choice, oven programming, and detector configuration. It also calls for detailed sample preparation methods, calibration strategies, and a comprehensive bill of materials along with maintenance procedures.

The project aims to develop a gas-chromatography system equipped with both a Thermal Conductivity Detector (TCD) and a Flame Ionization Detector (FID) for the separation and quantification of light hydrocarbons such as methane, ethane, ethylene, and acetylene. Key requirements include a design covering column selection, carrier gas choice, and programming to prevent signal overlap.
A detailed method for sample preparation and injection must yield sharp peaks, with calibration strategies and expected detection limits specified. Documentation should include schematic drawings, a bill of materials, and operating procedures, ensuring baseline-resolved peaks for the target analytes and sub-ppm detection limits.
