To install the ESI probe into the MS detector
CAUTION Take care when inserting the ESI probe into the probe heater. The capillary
protruding from the end of the ceramic sleeve and the ceramic sleeve itself are easily
damaged. In addition, you can contaminate the capillary if you let it touch the inner
surface of the probe heater as you insert the probe into the probe heater.
1. If you have not already done so, turn the probe heater off.
2. Turn the locking plate of the probe clockwise to the open position, and then carefully
slide the ESI probe into the probe heater.
3. Turn the locking plate counterclockwise to the closed position to lock the probe in place.
