Location: Searle Building - Room 340A

· Varian Saturn 2000 GCMS: installed with EI ion source; ideal for volatile and semivolatile organic molecules.

· Agilent 6130 LCMS: installed with DAD detector and ESI/APCI multimode ion source; majorly for molecular weight confirmation of synthetic compounds of organic and inorganic molecules and/or separation of reaction mixtures of organic molecules.

High Resolution Accurate Mass Spectrometry with Electrospray Ionization (HRA-ESI) or Electron Ionization (HRA-EI)

Location: Searle Building - Room 340A

· Agilent 6224 Tof: installed with ESI/APCI ion source; excellent for accurate mass measurements of synthetic compounds of both organic and inorganic molecules to meet publication requirements.

· Agilent 7200B Q-Tof GC: installed with EI ion source and MS/MS technique; meet publication requirement of accurate mass measurement for low boiling point organic molecules; excellent for targets, un-targets and unknowns; ideal for metabolomics, nature products, contaminants (pesticides, etc.) screening, etc.
