Gas Chromatograph Mass Selective Detector

Agilent Single Quadrupole Gas Chromatograph Mass Selective detector (GC/MS). Agilent 7890A GC with Agilent MSD 5975 MS using MassHunter software. A GC is used to separate low molecular weight chemicals using helium as a carrier gas. Constituents are separated at different rates based on their various chemical and physical properties as well as their interaction with the column stationary phase. As chemicals exit the column, they are identified using the Mass Spectrum. Located in Olney G-12.
