Selection Guide for Gas Chromatograph Mass Spectrometer
When selecting Gas Chromatograph Mass Spectrometer (GC-MS), customers should evaluate a range of parameters based on their application needs. The typical mass range of 1–1000 m/z allows analysis of low to high molecular weight compounds, making it suitable for diverse fields like environmental testing, forensics, and pharmaceuticals. A wide oven temperature range, often up to 450°C, supports the analysis of both volatile and thermally stable compounds. High sensitivity, often in the femtogram to picogram range, provides accurate trace-level detection. Additional features such as electronic pressure control (0–100 psi with ±0.002 accuracy), various ionization options (EI and CI), fast scan speeds, and compatibility with comprehensive spectral libraries (NIST, Wiley) enhance performance and flexibility. These selection ranges help customers choose a GC-MS system tailored to complex mixture analysis and specific research or industrial requirements.
