Using an Injector 135
6. Allow sufficient time for the sample to clear the injector before repositioning the
Load/Inject handle. Reposition the Load/Inject handle as follows:
• If you are operating in the gradient mode, or if the next sample is not ready to be
loaded, leave the handle in the Inject position.
• If you are operating in the direct or isocratic mode, or if the next sample is ready
to be loaded, turn the Load/Inject handle clockwise to the Load position.
7.1.2 Using a PowerLine Autoinjector
Note: For complete information on the Waters 717plus Autosampler, see the Waters
717plus Autosampler Operator’s Manual.
You configure a PowerLine autoinjector such as the Waters 717plus Autosampler on the
IEEE-488 bus. The autoinjector is under the control of the Waters 600 Controller.
Programming Considerations
When you make injections with a PowerLine autoinjector through either the Direct
Control mode or Operate Method mode:
• Set the autoinjector parameters to the desired values on the Autoinjector Setup
screen (see Section 4.4, Setting Up the Autoinjector).
• Specify the vial from which you want to make the injection:
– In the Vial # field, when in the Direct Control mode (see Section 5.1.3, Setting
Autoinjector Parameters)
– In the vial range, when in the Operate Method mode (see Section 6.4.3, Entering
Parameter Values in the Method Table)
• Specify the injection volume in the Inj Vol field.
• When programming a method table, specify the number of injections.
Injecting Samples
When you start the run or the method, the PowerLine autoinjector receives the sample
injection information from the controller, draws the sample from the appropriate vial, and
signals the controller when it makes the injection.
7.1.3 Using a Non-PowerLine Autoinjector
Note: For complete information on your non-PowerLine autoinjector, see the operator’s
manual included with the injector.
