CAUTION Take care when inserting the APCI probe into the probe heater. The capillary
protruding from the end of the probe is fragile and 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. Turn the locking plate of the probe clockwise to the open position, and then carefully
slide the APCI probe into the probe heater. See
