After operating the LTQ XL/ETD or LTQ Velos/ETD system, follow these procedures:

•

Placing the System in Standby Mode

•

Purging the Oil in the Fore Pump



To place the system in standby mode

1. Open the Tune Plus window; see the instructions on

2. Choose Setup > Reagent Ion Source to open this dialog box

3. Clear the Reagent Ion Source On check box.

When you clear this check box, the ETD source and reagent heaters go in standby mode

and the filament and vial heaters turn off. Simultaneously, a valve opens to allow nitrogen

gas to cool the reagent vials. This cooling nitrogen runs until the vials cool down to 70 °C

(158 °F). When you hear the sound of escaping gas, the cooling nitrogen has turned

on—this sound is a normal part of the instrument operation.

4. In the Tune Plus window, click the On/Off/Standby button to select the Standby mode.
