Operation
Using two injectors
70
To restart an aborted sequence from the point of interruption:
1. Identify the last sample vial that was run successfully. Check the vial
number of the last successful chromatogram.
2. Reset the parameter that identifies the first sample vial to the next vial
number.
3. Press the stop button to clear any faults.
4. Start the revised sequence from your controlling device. From the
multitechnique ChemStation, you can run a partial sequence to keep the
original sample numbers.
Using two injectors
Two-injector configurations have the following characteristics:
• Input and output signals are shared.
• The system sends only one injector ready signal to the GC when both
injectors are ready and one start signal at the beginning of the injection
stroke.
• The injectors can operate in the synchronous mode (both inject
simultaneously).
The capabilities of a two-injector configuration vary with the communication
device.
For information on using two injectors with standalone control or for
operation in asynchronous standalone mode, see chapter 4, “Standalone
Control.”
With a tray
The tray delivers sample vials to the front and back injectors according to the
run parameters. There is a separate set of run parameters for each injector.
The tray delivers vials to the front injector before the back injector.
