8.5 Perform Care Actions LAR | PROCESS ANALYSERS AG
8.5.11 Clean TIC Stripping Vessel
Precondition: - TIC stripping vessel is contaminated.
1. Take the screw cap on the TIC port.
2. Suck up the acid using a syringe.
3. Take all tube connectors for the TIC stripping vessel.
4. Take the TIC stripping vessel from the pipe clamps.
5. Place the TIC stripping vessel in an ultrasonic bath for 10 minutes for cleaning.
6. Carefully rinse out the TIC stripping vessel with deionised water to remove all residues from the frit.
7. Refit the TIC stripping vessel into the pipe clamps.
8. Reconnect all tube connectors for the TIC stripping vessel.
9. Screw the screw cap back onto the TIC stripping vessel.
8.5.12 Clean Gas Cooling Pipe
Precondition: - Gas Cooling Pipe is contaminated
1. Unscrew the 3 or 6 connection pieces with the tube connectors.
2. Carefully pull the relevant gas cooling pipe upwards out of the cooler guide.
3. For cleaning, use a laboratory bottle filled with deionised water, or a single-use syringe, and as
required a small bottle brush, a pipe cleaner or a moist cotton cleaning cloth.
4. Use a soft paper towel to clean the surface of the gas cooling pipe.
5. Rinse the gas cooling pipe from inside by gradually spraying deionised water into the openings of
the cooling tube.
6. If contamination levels are high, glass cleaning agents can also be used (however the cooling tube
must be rinsed out afterwards with at least 200 ml of deionised water).
7. Use a soft paper towel to dry the surfaces of the gas cooling Pipe.
8. Dry the side tube connectors of the gas cooling pipe using a pipe cleaner.
9. Coat the skin surfaces of the gas cooling pipe with silicone-free, heat-conductive paste.
10. Use a soft paper towel to clean the seats of the cooler.
11. Push the gas cooling pipe back into the seats of the cooler.
12. Connect the tubes correctly back to the tube connectors of the gas cooling pipe.
8.5.13 Clean Running Rails (XY-System)
Precondition: - Running rails are contaminated.
Use a lint-free paper towel to remove decontamination from the XY running rail.
Warning
Damage to the gas cooling pipe
Do not pull the gas cooling tube out of the welded hose connection as the con-
nection could break off.
The images of the gas cooler must not be cleaned with sharp objects, as other-
wise the transition surface from the cooler to the gas cooling tube will be da-
maged.
Pay attention to the correct connections of the hose connections, since a
change of the hoses can lead to wrong measuring results.
