Waters (Micromass) LCT®: electrospray ionization, time-of-flight (TOF)
Where possible samples are dissolved in methanol and sprayed with a sample cone voltage of 20. For exact mass measurements (EMM), an aliquot of a known compound (lock mass) is added to the sample and resprayed. The purchase of the LCT® was partially funded by NSF Award #CHE-9974839 to the Department of Chemistry.
