Lab Exercise: Introduction to the HPLC ChemStation

Scheduler

The Scheduler may be used to make your ChemStation automatically execute

commands on a one time, daily, daily weekday, or weekly basis. You may

schedule events such as controlling a valve, loading a method or sequence,

starting a sequence, or initiating a blank run. As a command is processed, the

Scheduler records the completion status as accepted, rejected, not allowed, or

instrument not found in the Results column so that the progress can be reviewed

easily. Note that the events associated with running an analysis or sequence take

precedence over the execution of scheduler events.

1) From the Windows Start button find All Programs, Agilent ChemStation,

then Instrument 1 Offline. The ChemStation application must be open for

the Scheduler to work. Now select the Scheduler from Start, All Programs,

Agilent ChemStation.

2) Using the drop box in the upper left hand corner of the Scheduler, select the

instrument to be scheduled.

3) A blank schedule for that instrument will appear. The entries include:

Date: Enter the first date this command should be sent, current date to

one year in advance.

Time: Using the 24-hour clock format (13:00 is 1:00 PM), enter the Time

this command should be sent.

Command: Enter the command you want to be sent. Command help is found

in the ChemStation under the Help menu.

Mode: Select what day(s) this command should be sent.

Result: Lists completion status of each command sent to an instrument.

4) For practice, you will make the ChemStation logbook appear on the screen

using the Scheduler. Enter the current date. Enter a time approximately 2

minutes from the current clock time (found in the lower right hand corner of

the screen). Type: Logbook On in the Command box. The mode will be Do

Once.

5) The selected commands will be stored for use once they are saved. Select the

Save tool from the toolbar.

6) Minimize the Scheduler and wait to see if the logbook appears automatically.
