Gas Chromatography (GC) with FID / MECD / TCD / NPD
At SIMA LABS, we employ cutting-edge Gas Chromatography (GC) systems integrated with a range of advanced detectors including Flame Ionization Detector (FID), Micro Electron Capture Detector (MECD), Thermal Conductivity Detector (TCD), and Nitrogen-Phosphorus Detector (NPD). This diverse detector configuration allows for the precise identification and quantification of volatile and semi-volatile organic and inorganic compounds across a wide range of industries. Whether analyzing hydrocarbons, halogenated compounds, permanent gases, or nitrogen/phosphorus-based residues, our GC systems deliver high sensitivity, reproducibility, and regulatory compliance—making them essential tools for pharmaceutical, environmental, food, forensic, and industrial testing.

Applications
Gas Chromatography (GC) equipped with FID, MECD, TCD, and NPD detectors is a powerful analytical technique used across pharmaceutical, environmental, food, petrochemical, and forensic industries. It enables accurate detection and quantification of volatile and semi-volatile organic and inorganic compounds—supporting quality assurance, regulatory compliance, and safety in diverse sample matrices through high sensitivity, selectivity, and detector-specific performance.
Each detector serves a unique function:
FID detects hydrocarbons and most organic compounds.
MECD is ideal for halogenated VOCs and pesticides.
TCD is suited for permanent gases like CO₂, O₂, and H₂.
NPD is selective for nitrogen- and phosphorus-containing compounds.
Our systems can detect compounds down to parts-per-billion (ppb) or lower, depending on the matrix and detector used.
Yes, using direct injection, headspace, or purge & trap methods, we can analyze a variety of sample types including liquids, solids, and gases.
Absolutely. All GC analyses follow validated methods as per EPA, ICH, USP, FSSAI, and ISO guidelines.
Yes, we provide method development, validation, and tailored testing based on your specific product or regulatory requirements.
