Novatek Analytic Ethylene Oxide Residue Gas Chromatography (Face Mask Testing)

This gas chromatography system is designed to detect ethylene oxide (EO) sterilization residues in products such as face masks, medical devices, and sterile packaging. The hydrogen flame ionization detector (FID) measures organic volatile compounds with high sensitivity and can optionally be equipped with alternative detector types.

The instrument is configured with a 30m×0.32mm×0.5µm chromatographic column specifically selected for ethylene oxide analysis and a 20-position headspace autosampler, which automates the sample preparation and analysis workflow. The temperature control system features six-zone regulation operating between 4℃ and 450℃ with ±0.1℃ accuracy, enabling creation of 16-step programmed heating profiles.

Detector performance specifications include: ≤3×10⁻¹²g/s (n-hexadecane) detection limit, ≤2×10⁻¹⁴A baseline noise, and ≤1×10⁻¹³A/30min baseline drift, ensuring reliable detection of low-level EO residues. Real-time temperature and chromatogram monitoring via LCD display; professional software generates PDF analytical reports.

Suitable for petrochemical, pharmaceutical, medical device manufacturing, commodity inspection, and environmental analysis laboratories determining ethylene oxide and other organic solvent residues.
