EziLab offers the Gas Chromatography Mass Spectrometry EZL-GCMS101, a GC-MS system built around an all-metal quadrupole and a dual-filament electron ionization source. It covers 1.5 to 1200 u at unit resolution, scans up to 20,000 u/s, and holds mass axis drift below 0.10 u over 48 hours with a 10⁷ dynamic range. A 250 L/s turbomolecular pump with quick-lock restart, an ultra-inert flow path, and a 1,500:1 signal-to-noise ratio round out the hardware. SCAN, SIM, and combined SCAN/SIM modes, with SIM tables of 64 ions across 128 groups, let this GC-MS instrument screen unknowns and quantify trace targets in the same run. MassExpert software adds one-touch autotune, batch processing, and trend charts, while NIST library matching with deconvolution speeds compound identification. Built-in report templates turn results into finished reports quickly. Environmental testing labs measure pesticides, VOCs, and semivolatile pollutants, while food and beverage centers screen residues and flavor compounds. Forensic and toxicology units identify drugs and poisons, clinical diagnostic labs analyze metabolites, and pharmaceutical QC teams check impurities and residual solvents. Academic chemistry programs and materials researchers use this quadrupole GC-MS for teaching and routine characterization work.
