AELAB GC-MS 6800 Gas Chromatograph–Mass Spectrometer for High-Performance Analytical Testing

The AELAB GC-MS 6800 gas chromatograph–mass spectrometer is a cost-effective analytical system incorporating multiple patented technologies for routine and advanced laboratory applications. It is widely used in industrial inspection, food hygiene, environmental protection, and pharmaceutical analysis. The system integrates high-sensitivity mass detection, reliable gas chromatography, and a robust vacuum architecture to meet high-throughput analytical demands.

The GC-MS 6800 employs advanced electronic pressure control, a high-efficiency EI ionization source, and stable turbo molecular pumping to deliver reproducible results across complex matrices. It supports industrial users, research laboratories, and public security institutions requiring precise identification of organic compounds, contaminants, and trace residues.

⚙️ Design & Construction

The AELAB GC-MS 6800 combines a high-temperature GC oven, split/splitless injector, and electronically regulated EPC module with a quadrupole MS analyzer equipped with a high-energy dynode electron multiplier. The ion source operates from 100°C to 350°C, while the GC-MS interface supports temperatures up to 450°C to ensure efficient analyte transfer. A turbo molecular pump (67 L/s) stabilizes vacuum conditions to maintain detector sensitivity and mass stability (±0.10 amu/48 hrs).

🔬 Working Principle / Testing Method

The system performs chromatographic separation under EPC-regulated pressure conditions before compounds enter the EI ion source for electron-impact ionization (5 W–250 eV adjustable). Generated ions are filtered by a quadrupole mass analyzer providing unit resolution across 1.5–1000 amu. Full-scan and SIM acquisition modes enable identification, quantification, and structural interpretation of volatile and semi-volatile compounds. Data are collected through high-speed acquisition electronics for accurate peak integration and mass spectral analysis.
