Detector: Dual-channel Thermal Conductivity Detector (TCD)

Chromatographic columns: Dual-channel parallel separation, enabling simultaneous analysis of inorganic components and hydrocarbon components in a single run

Carrier gas: High-purity helium with consumption less than 20 mL/min

Analysis cycle: Standard 5 minutes per cycle; cycle parameters configurable by users

Inorganic components: N₂, CO₂ (0.01~100%, minimum detection limit 0.005%)

Light hydrocarbons: CH₄, C₂H₆, C₃H₈, isobutane (iC4), n-butane (nC4), neopentane, isopentane (iC5), n-pentane (nC5), heavy fractions C6+

Optional expansion: H₂S hydrogen sulfide separation module (for sulfur-containing natural gas)

Calorific value repeatability: ±0.125 Btu/1000 Btu (ambient temperature); ±0.25 Btu/1000 Btu across full temperature range

Minimum Detectable Quantity (MDQ) of components: 0.001~0.005 mol%

Calculation outputs: Gross / net heating value, Wobbe index, relative density, compression factor, Velocity of Sound (VOS), gallons per thousand cubic feet of condensate (GPM)
