To flush the inlet components
1. Turn off the liquid flow from the syringe pump.
2. Place the mass spectrometer in Standby mode.
3. Remove the syringe from the syringe pump as follows:
a. Lift the syringe holder off of the syringe.
b. Press the pusher block’s release knob and slide the block to the left.
c. Remove the syringe from the holder.
d. Carefully remove the syringe needle from the Teflon tube on the syringe adapter
assembly.
4. Clean the syringe as follows:
a. Rinse the syringe with a solution of 50:50 methanol/water.
b. Rinse the syringe with acetone several times.
5. Flush the sample transfer line, sample tube, and spray insert as follows:
a. Load the cleaned syringe with a solution of 0.1% formic acid in 50:50
methanol/water (or another appropriate solvent).
b. Carefully reinsert the syringe needle into the Teflon tube on the syringe adapter
assembly.
c. Slowly depress the syringe plunger to flush the solution through the sample transfer
line, sample tube, and spray insert.
d. Remove the syringe needle from the syringe adapter assembly.
This completes the procedure to flush the inlet components.
Purging the Oil in the Forepump
Purge (decontaminate) the oil in the forepump daily to remove water and other dissolved
chemicals, which can cause corrosion and decrease the lifetime of the forepump. For
instructions, refer to the forepump’s documentation.
The best time to purge the oil is at the end of the working day after you flush the inlet
components. Remember to close the purge valve before continuing normal operation.
