Multimode Source for 6100 Series Single Quad LC/MS User Guide 15

Basic Operation and Maintenance 1

To turn off the instrument

Before you begin, check that:

• You have completed tuning and data acquisition and you have saved all

data as needed.

Follow these steps to vent and completely power the instrument off.

1 Use the MSD Vent dialog box to vent the MSD instrument.

In the Diagnosis View, select Maintenance > MSD Vent

2 When the vent cycle is completed, exit the ChemStation program.

3 Turn off the power switch on the front of the LC/MS.

WARNING

The quadrupole cools very slowly and will likely be near 100°C when the vent cycle

is complete. The drying gas heater and APCI vaporizer heater will also still be hot.

Wait for the instrument to cool off before continuing.

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.
