Gas Chromatograph - Mass Spectrometer (GC-MS)
Description:
Agilent Model 8890 GC System with Single Quadrupole Mass Spectrometer (5977B MSD) analyzer is used for the separation and identification of thermally stable volatile compounds. The GC consists of Split / Splitless (SSL) injectors and capillary columns for different applications. NIST spectral library search is also available.
Major Specifications:

Area repeatability: <0.5%
Retention time repeatability <0.008%
· Inlet Split ratio: 7500:1
· Mass filter: Heated monolithic hyperbolic quadrupole
· Ionization modes: Electron Impact(EI) and Chemical Ionization(CI)
· Mass Range: (m/z) 1.6 −1,050 amu
· Mass resolution: Unit mass
· Mass Accuracy: 1 μL injection of 100 a pg/μL OFN standard scanning from 50.350 u will give its monoisotope at m/z 271 ±0.005
· Spectral Accuracy: 1 μL injection of a 100 pg/μL OFN standard scanning from 50.350 u will give 99.0% spectral accuracy
· Ion source temperature: 150 -350°C
· Quadrupole Temperature: 106-200°C
· Detector Triple-Axis Detector with high energy dynode and long life electron multiplier
