7. Pull the ion source gently away from the vacuum interface.
Note:
Be careful not to lose the O-rings that are installed on the vacuum interface.
8. Put the ion source on a clean, secure surface.
Clean the Ion Source Surfaces
WARNING! Electrical Shock Hazard. Remove the ion source from the mass
spectrometer before starting this procedure. Follow all electrical safe work
practices.
Prerequisite Procedures
•
.
Clean the surfaces of the ion source after a spill or when they become dirty.
Wipe the surfaces of the ion source with a soft, damp, cloth.
Clean the Probe
Flush the ion source periodically, regardless of the type of compounds sampled. Do this by
setting up a method in the control software specifically for performing a flushing operation.
1. Change to a mobile phase that is 1:1 water:acetonitrile or 1:1 water:methanol.
2. Adjust the position of the probe so that it is as far from the orifice as possible.
3. In the control software, do the following:
a. Create an MS method.
b. Set the ion source temperature between
500
° C and
600
°C.
c.
Set ion source gas 1 and ion source gas 2 to at least
40
.
d. Set the flow rate of the gas for the Curtain Gas interface to the highest setting possible.
4. Wait until the temperature setpoint is reached.
5. Make sure that the probe and sample tubing are flushed thoroughly.
