LC-MS InstrumentsThe JEOL AX505HA can be connected with
a Waters 625 LC having a LINEAR UV/VIS detector. Flow-FAB, ESI, and APCI ionization
interfaces are available. Flow-FAB and ESI require substantial solvent splitting with optimum flow rates of 3 uL/min
and 10 uL/min, respectively. Flow-FAB requires glycerol (1%) in the mobile phase. APCI can accomodate flow rates up
to 1 ml/min with no splitting, and requires no additives.
The Quattro LC can be connected to a Waters Alliance LC system having a photodiode array
detector. ESI and APCI are available for the interface to the mass spectrometer.
LC/MS PolicyThe MS Facility strongly suggests
that LC separation conditions be worked out prior to sample submission.
LC/MS ColumnsThe table below lists the LC columns owned by the MS Facility.
Submittors must provide LC columns not appearing in the table below.
