To remove the multimode source

To remove the multimode source

Do the following steps to remove the multimode source.

1

Turn off the multimode source temperatures and flows:

a

Change the 

Context

 view to 

Acquisition

.

b

Click the 

MS QQQ

 tab.

c

Turn off all voltages and temperatures in the 

Source

 tab.

d

Wait approximately 20 minutes for the source to cool down. 

2

Wait approximately 20 minutes or until the source is cool.

3

Open the CDS door at the front of the MS to access the cables. 

4

Disconnect the ESI high voltage charging electrode cable. 

5

Disconnect the APCI Needle Interlock, and multimode HV cable. 

6

Unscrew the nebulizer gas line from the nebulizer.

7

Unscrew the LC sample tubing from the nebulizer.

8

Open the latch on the source and open the source.

9

Remove the multimode source from the spray chamber mount.

10

Place the source shipping cover on the source.

WA R N I N G

Do not touch the multimode source or the capillary cap. They may be very hot. Let 
the parts cool before you handle them.

WA R N I N G

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.

WA R N I N G

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.
