To Clean the EI Hydronert Source
.
Replacement of Hydronert source parts is recommended if a reduction in
sensitivity is observed that cannot be recovered by performing maintenance on
the GCMS system. This maintenance should include items know to cause
sensitivity problems such as syringe replacement, syringe wash replacement,
inlet cleaning, inlet consumables replacement, column replacement, and rough
pump maintenance.
The coated parts of the Hydronert source shown in the figure below are the
parts labeled 17, 12, 3, 4, 10 and 9. After disassembly, if an examination of the
12-Repeller and 4-extractor lens shows a buildup of residue, replace these parts.
Additionally, replacement of the insulators, 5-Extractor Lens insulator and
11-Repeller Insulator, is recommended. See Table 18 on page 177 for a list of
part numbers.
Do not abrasively clean the coated parts of the source. Abrasives will destroy
the coating and require a new part to be purchased.
