Gas Chromatograph
Gas Chromatography (GC) is a premier analytical technique used to separate, identify, and quantify volatile compounds within a complex mixture. Its high resolution and sensitivity make it an indispensable tool in fields such as environmental testing, pharmaceutical quality control, and food safety analysis, providing the critical data needed for research and compliance.

2. Q: Which GC Detectors should I choose?
A: Please refer to the table below:
Table 1: Comparison of Common GC Detectors
| Detector | Working Principle | Specificity | Sensitivity | Destructive? | Common Applications/Analytes |
| Flame Ionization Detector (FID) | Burns organic compounds in a hydrogen/air flame, creating ions that generate a current. | Selective for carbon-containing compounds. Does not respond to water, CO2, or permanent gases. | High (~0.1 ng) | Yes | Most organic compounds, hydrocarbons, pharmaceuticals, food analysis. |
| Thermal Conductivity Detector (TCD) | Measures the change in thermal conductivity of the carrier gas as an analyte passes over a heated filament. | Universal. Detects any compound that has a different thermal conductivity than the carrier gas. | Low (~10 ng) | No | Permanent gases (O2, N2, CO2), water, light hydrocarbons, gas analysis. |
| Electron Capture Detector (ECD) | Measures the capture of electrons by electrophilic compounds (e.g., those with halogens) from a low-level radioactive source. | Highly selective for compounds with high electron affinity. | Very High (~0.01 pg) | No | Halogenated compounds (pesticides, PCBs), environmental analysis, organometallics. |
| Mass Spectrometer (MS) | Ionizes eluting compounds and separates the resulting fragments based on their mass-to-charge () ratio. | Universal. Provides a mass spectrum that acts as a “molecular fingerprint” for definitive identification. | Very High | Yes | Definitive identification of unknown compounds, complex mixture analysis, forensics, environmental, pharmaceuticals. |
