How to Submit a Shutdown Method in OpenLab 2.x

Answer

This Information Applies To: Agilent OpenLab CDS 2.x controlling Agilent LC Systems

Issue

This article outlines an instruction on how to submit a shutdown method on OpenLab CDS 2.3 or above.

Background

Submit a shutdown run to the run queue that will shut down Agilent LC instrument after all other runs in the run queue are complete.

Steps to Follow

1. Create an acquisition method (.amx file) to use it as a shutdown method. (See Figure 1)
   See Table 1 for suggested instrument parameters for the LC instrument shutdown method.
   
   

   
   
   
   Figure 1: Create a shutdown amx file

   
    
   Note: The following recommendations are just a general guideline. Method conditions may be different according to the application, installed column, and instrument configuration.

   
   Table 1: Instrument Parameters for LC shutdown 

   Pump	Flow: 0 mL/min, or a low flow compatible with your application Stoptime: 1 min
   Column Oven	Temperature left: Ambient Temperature right: combined Stoptime: As Pump/ Injector
   DAD/ MWD/ VWD	In the Advanced section, go to the Lamps on required for acquisition, and clear the UV lamp check box Stoptime: As Pump/ Injector
   FLD	Signal: clear the Acquire Signal check box In the Special setpoints section, go to Lamp and clear Lamp on required for analysis check box Stoptime: As Pump/ Injector
   RID	Optical Unit Temperature: Not controlled, or the same temperature as the analytical method to allow rapid system equilibration for next run Signal: Clear the Acquire Signal check box Stoptime: As Pump/ Injector
   ELSD	Stoptime: As Pump/ Injector Switch off: deselect Switch off at the end of the run; deselect Switch off on program exit For G4260B, G4261B, G7102A: Output Signal: deselect Acquire Signal

   
   

    

   Tips: If buffer is used in the mobile phase, flush the system with a solvent containing water instead of buffer, according with your method and column compatibility.

2. Click Browse to select the shutdown acquisition method (Figure 2).
   The shutdown method can only be submitted in the Run Queue.

3. Select the acquisition method and click Open. (See Figure 3)
   If the method is obsoleted, then the shutdown run cannot be submitted.

4. Click Submit Shutdown Run. (See Figure 4)

5. The shutdown run is added to the end of the run queue and is highlighted in yellow. You cannot submit another shutdown run until the submitted shutdown run is complete. (See Figure 5)

   Confirmation: Once the shutdown run begins, the shutdown process is recorded in the Activity Log. (See Figure 6)
