To open the multimode source
Open the multimode source to access the end cap and the capillary cap for
cleaning and inspection.
1 Open the spray chamber cover by pulling the latch.
The high voltage automatically turns off when the chamber door is opened
so that no high voltages are present within the chamber.
2 Check that the vaporizer temperature sensor is straight and extends 15mm
from back of chamber.
3 Check that the separator is aligned vertically.
4 Check that the APCI corona needle is in and extends approximately 3mm
from the corona guide.
5 Check that the source is clean.
6 Close and latch the multimode source.
WARNING
Do not touch the multimode source or the capillary cap. They may be very hot. Let the
parts cool before you handle them.
WARNING
Never touch the source surfaces, especially when you analyze toxic substances or
when you use toxic solvents. The source has several sharp pieces which can pierce
your skin including the APCI corona needle, vaporizer sensor and counter current
electrode.
WARNING
Do not insert fingers or tools through the openings on the multimode chamber. When
in use, the capillary and capillary cap are at high voltages up to 4 kV.
