To Pumpdown the MSD in CI Mode

This procedure assumes that the instrument will eventually be PCI tuned using
methane after the system is stable.

Procedure

Follow the instructions for the EI MSD. (

See

“To Pumpdown the MSD”

page 139.)

After the software prompts you to turn on the GC/MSD interface heater and
GC oven, perform the following steps.

In the

Manual Tune

dialog, click the

Values

tab to monitor that the pressure is

decreasing (Hi-Vac gauge option installed).

In the

Manual Tune

dialog, click the

CI Gas

tab, then in the

Valve Settings

area close

Gas Valve A

Gas Valve B

, and the

ShutOff Valve

Verify that

PCICH4.U

is loaded (top left in

Manual Tune

dialog) and click the

Values

tab to accept the temperature setpoints.

Always start up and verify system performance in PCI mode before
switching to NCI.

Set the GC/MSD interface to 280 °C. (See

Table 12

on page 147.)

Set

Gas A (methane)

to 20%.

Let the system bake out and purge for at least 2 hours. If you will be running
NCI, for best sensitivity, bake out the MSD overnight.
