Vanquish Charged Aerosol Detectors Operating Manual
For successful maintenance and service procedures, follow these rules
and recommendations:
• Before starting maintenance or service procedures, shut down the
detector when instructed to do so.
•
Use only the replacement parts specifically authorized and qualified
for the detector by Thermo Fisher Scientific. For ordering
information, see section 10.4 Consumables and Replacement Parts,
page 171.
• Follow all instructions step by step and use the tools recommended
for the procedure.
•
Before opening the flow path to replace capillaries in the system,
turn off the pump flow and wait until the system pressure is down to
zero.
•
Dirty components can contaminate the chromatography system.
Contamination leads to poor performance of the modules and entire
system or can even cause damage to the modules and system.
Therefore:
♦
Always wear appropriate gloves.
♦
Place the components only on a clean, lint-free surface.
♦
Keep your tools clean.
♦ Use only lint-free cloth for cleaning.
