Maintaining the Probe Heater

Removing the Probe Heater

Thermo Scientific
If you use the instrument primarily in the APCI mode, clean the probe heater on a monthly
basis. If you use the instrument primarily in the ESI mode, you have to clean the probe heater
less frequently.
Occasionally, tension or sharp edges on the probe latching plate can cause breakage of the
PEEK mounting pins. Use the parts supplied in the Probe Heater Repair Kit
(P/N 60111-62010) to repair the probe.
To clean or repair the probe heater, follow these procedures:
1. Removing the Probe Heater
2. Cleaning the Probe Heater or Replacing the Detent Screw Insulator
3. Installing the Probe Heater
To remove the probe heater from the probe mount
1. Remove the ESI or APCI probe. Refer to
"Removing the APCI Probe"
CAUTION Wait for the probe heater to cool before you remove it.
2. Rotate the black knobs of the probe heater outwards 90 degrees, so that they face away
from each other. See
The black knobs are connected to locking cams. When the black knobs are facing away
from each other, the cams are in the unlocked position and you can pull the probe heater
out of the probe mount.
