Preparing the Syringe Pump for Calibration
Use the syringe pump to infuse the EMRS calibration solution into the H-ESI source. For a
list of calibration supplies, see Appendix E, “Replaceable Parts.”
Before you begin, follow the procedure in Appendix B, “Setting Up the Syringe with the
Syringe Pump.”
Risk of electric shock: This instrument uses voltages that can cause electric shock and /or
personal injury. While operating the instrument keep the covers on.
CAUTION Do not wear nitrile gloves when you are working with the calibration solution,
EMRS. Nitrile gloves are made with diphenylguanidine which is soluble in EMRS. If
diphenylguanidine contaminates the EMRS, a peak at m/z 212 will be in the spectrum.
IMPORTANT To prevent the EMRS from degrading, do the following:
• Do not return any EMRS back to the original vial.
• Do not store EMRS in a glass syringe. Discard unused EMRS and rinse the syringe
with acetonitrile.
• If you observe degradation products in the EMRS mass spectrum, rinse the sample
line (including the fittings, syringe, tubing, and union) with acetonitrile.
