Item Description

splitless runs in which the split vent is opened.

Injector EFC, Gas Saver Flow The lowest system flow rate that will be

maintained during the gas saver period. This

has a range of 1-100 mL/min and defaults to

20 mL/min.

Injector EFC, Gas Saver Timeout A non-zero value entered for this parameter

will cause the system to initiate a timer once a

method is activated. If no system actions such

as a run start or another method activation

occurs before the Gas Saver Timeout is

reached, then the system will reduce the flow

through the system to the Gas Saver Flow. A

method activation action will clear the Gas

Saver Flow and bring the system to Ready for

subsequent injections. A zero value entered

for the Gas Saver Timeout will cause the Gas

Saver Flow to be ignored and no Gas Saver

actions will be performed.

Injector EFC, Auto Calibrate EFC

Flow

Automatically calibrate the EFC system.

When it is finished, the screen will display

either a successful completion or detected

problem message. No other GC functions can

be performed during AutoCalibration. Note

that AutoCalibration should be done on a

semiannual basis.

Injector EFC, Calibrate Septum

Purge Flow

Calibrate the septum purge. After

installing a new column, the septum

purge should be calibrated. Set the

desired column head pressure. Then

measure the actual septum purge flow

rate and enter this value in the septum

purge field. The septum purge flow rate is

adjustable but is typically set at 3 - 5

mL/min.

Septum Purge Calibration, Desired

Head Pressure

The desired column head pressure in psi.

Range is 0.1 - 100 psi.

Septum Purge Calibration,

Measured Flow Rate

The septum purge flow rate is adjustable but

is typically set at 3 - 5 mL/min.

Print Actual Sends the 3900 setup parameters to the

default printer.

Close & Update Saves the changed parameters and

reinitialize the 3900 with the new parameters.

AutoSampler, Type None, 8400, 8410

Displays the type of autosampler that is

connected to the 3900 GC.

AutoSampler, Syringe Volume

5 L, 10 L and 100 L.

Enter the syringe volume you will install and

use with your CP-8400/8410. The 3900 will

use this value to set the correct entry

selections and any needed internal settings to

correctly use the indicated syringe size.

Incorrectly setting this parameter may cause
