Gas chromatography (GC) is a highly sensitive analytical technique used in laboratories worldwide for separating and analyzing volatile compounds. To ensure accurate and reliable results, the purity of nitrogen gas used as a carrier gas, detector gas, or purge gas is critical.
Why Nitrogen Purity Matters in GC?
Baseline Stability: Impurities like oxygen, moisture, or hydrocarbons can cause baseline noise, peak distortion, and false readings.
Column Protection: Oxygen (>1 ppm) can degrade GC columns, reducing their lifespan and separation efficiency.
Detector Performance: High-purity nitrogen ensures optimal sensitivity in detectors like TCD (Thermal Conductivity Detector) and ECD (Electron Capture Detector).
For most GC applications, nitrogen purity of ≥99.999% (5N) is required, with:
Oxygen (O₂) < 1 ppm
Moisture (H₂O) < 3 ppm
Hydrocarbons (THC) < 0.1 ppm
