To remove the multimode source

Do the following steps to remove the multimode source.

1Set the source temperatures for vaporizer heater and drying gas heater to minimum values to cool the source.

Use the Tune > Instrument > Edit Spray Chamber menu item to display the Edit Spray Chamber dialog box. Set the drying gas flow, nebulizer gas flow, drying gas temperature and the vaporizer temperature to minimum values.

Do not touch the multimode source or the capillary cap. They may be very hot. Let

the parts cool before you handle them.

 

 

 

 

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.

 

 

 

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.

 

 

 

 

 

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.
