EziLab offers the Gas Chromatography Mass Spectrometry EZL-GCMS100, a single quadrupole GC-MS system that separates volatile and semi-volatile compounds and identifies them by mass spectrum in one run. Choose it when GC with FID or ECD can quantify targets but cannot confirm what an unknown peak is. The quadrupole covers 1.5 to 1000 amu at unit mass resolving power, scans at up to 10,000 amu/s for fast peaks, and holds mass stability to ±0.10 amu over 48 hours. An EI source adjustable from 5 to 250 eV and 100 to 350°C, a high energy dynode electron multiplier, and a 67 L/s turbomolecular pump deliver full scan sensitivity of S/N ≥ 30:1. The GC oven runs from 4 to 450°C at up to 120°C/min across 7 ramps and 8 hold steps, with electronic pressure control in CV and CC modes from 0 to 100 psi, and split/splitless injection up to 1000:1. Pharmaceutical labs test residual solvents and trace impurities, environmental agencies screen VOCs and contaminants, forensic and food safety teams confirm drug residues, petrochemical units characterize complex mixtures, and semiconductor labs check wafer and plastic extract contamination. Confirming an unknown peak needs the mass range to reach your target compound, so check the heaviest ion you expect against the 1000 amu ceiling in the Chromatograph category and GC MS range.
