Performing a Leaks Check (Capillary/Packed/UFM Columns)

OPERATING SEQUENCE
Performing a Leaks Check (Capillary/Packed/UFM Columns)
This procedure allows to check for leaks on both injector and detector sides and it
is suitable for capillary, packed and UFM columns.
Before starting this sequence, install the column into the injector port and the
detector base body.
Materials needed:
•
•
•
1. In case the column is already installed, cool down the injector and the detector
2. Only for FID, NPD, FPD: remove the detector. Do not remove ECD detector.
3. Only for FPD: remove the jet. In case of capillary columns, use typewriter
4. Finger tighten the relevant blind cap (fitted with a silicon seal) on the detector
5. Only for ECD: remove the chimney and seal the line with the relevant blind
6. Turn off any H
7. Press LEAK CHECK to enter Leak Check menu.
