An Aerodyne/Tofwerk L-Time-of-Flight CIMS that is used to identify the chemical formula of neutral gas-phase compounds. We use it with a range of different chemical reagent ions, from protonated ethanol clusters to toluene. The reagent ions are selective for different chemical classes; for example, protonated ethanol clusters are sensitive to organic nitrogen compounds. This CIMS has high temporal resolution, high mass resolving power, and high sensitivity.
The same Aerodyne/Tofwerk L-Time-of-Flight mass spectrometer (pictured with Aroob), except the ionization regime is removed. Ambiently charged positive and negative ions are measured with high temporal resolution and mass resolving power - even with the low signals that are associated with ambient ions.
A Dionex DX500 IC that is used by our lab to identify ions in aqueous solutions.
