Commands and Tips for Third-Party Devices
Agilent 1100/1200 HPLC System: Pump

In addition to (or different from) the standard pump commands (see Commands for Controlling Dionex Devices  Dionex Pumps) and the general commands for the 1100/1200 HPLC systems (see  Agilent 1100/1200 HPLC System: General), the following commands and properties are available (please note that the display Filter level determines which commands and properties are displayed):

If one of the pressure limits is exceeded, Chromeleon turns off the flow.

Agilent 1200 binary pump SL:

0.0 - 600.0

 

Value

Reports the current pump pressure.

 

LowerLimit

Lower Pressure Limit.

Note: The pump flow will not be stopped, if the current pump pressure never exceeds the defined lower limit. This means that a 'real' pressure drop must occur to trigger a flow stop.

 

UpperLimit

Upper Pressure Limit

PrimaryChannel

autom., A, B, C, D

(Quaternary LPG pump only) Select the channel from which the pump shall draw liquid first. The pump starts with drawing half the volume required for the composition, then draws the required volume from the other channels, and then draws the second half of the volume required for the first channel.

Automatic selects the channel with the maximum percentage.

SolventFillingX

0.00 l - 1000.00 l

* Enter the volume of solvent originally added to the bottle.

(Depending on the pump type, X = A1, A2, B1, B2 or A, B, C, D, respectively.)

SolventLeftPump

A1, A2

Eluent of the left pump. (Available only for the binary pump.)

SolventNotReady
Limit

0.05 l - 1000.00 l

* Determine the minimum liquid level.

SolventRightPump

B1, B2

Eluent of the right pump. (Available only for the binary pump.)

Stroke

autom., 20..100 µl

Pump stroke (Available only for the isocratic and quaternary pumps.)

StrokeLeftPump

autom., 20..100 µl

Stroke of the left pump. (Available only for the binary pump.)

StrokeRightPump

autom., 20..100 µl

Stroke of the right pump. (Available only for the binary pump.)

Rear Seal Wash Commands

The following commands are available only if the pump is equipped with the rear seal wash option and the Rear Seal Wash check box is selected on the Options tab page in the Server Configuration:

 Tip:  

This function is available only if the Rear Seal Wash option is installed for the pump.

 

Command

Description

System

Specifies a wash option: Off, Single, or Interval.

Duration

Specifies the duration of a single wash. This command is associated with the Single function of the System command.

Interval

Specifies the duration of the entire wash interval, i.e., the idle period and run time of the pump. This command is associated with the Interval function of the System command.

On Time

Specifies the actual run time of the pump during a wash period. This command is associated with the Interval function of the System command.

 Tip:

The time specified here may not exceed 70% of the duration specified under Interval.

Diagnostic Commands

Note:

Pump diagnostic commands are available for Agilent 1100 HPLC Systems only.

 

Command

Description

CountDown

Keeps the specified flow rate for the CountDown time. (The default setting is 0.00 min. The allowed range is 0.00 to 99,999.00 min.)

LeakTestInit

Prepares the pump for the leak test by moving pistons A1 and B1 of the quaternary pump and/or piston 2 of the binary pump to the top of its stroke.

LeakTestRun

Performs a leak test.

 Tip: 

Dionex recommends performing the command from the related diagnostic panel (see  Agilent 1100 HPLC System Diagnostics: Leak Test).

PressureTest

Performs a pressure test.

 Tip:  

Dionex recommends performing the command from the related diagnostic panel (see  Agilent 1100 HPLC System 1100 Diagnostics: Pump Pressure).
