Operation
Using two injectors
72
Figure 44. Synchronous N-1 injection mode
To inject the same sample into the front and back inlet in the same run, you
must do the following:
1. Prepare two sets of sample vials, two vials for each sample.
2. Place the sets in two different locations in the quadrants.
3. Set up the sequence parameters so that the tray delivers the first bottle of
one set to the front injector and the first bottle of the other set to the back
injector.
For example, with ten samples, you must have 20 vials (two vials for each
sample). Place one vial of each in tray positions 1 to 10. Place one vial of each
in tray positions 11 to 20. Set the first vial position for the front injector to 1
and the last vial position to 10. Set the first vial position for the back injector to
11 and the last vial position to 20.
Without a tray
The injectors go through the same motions as with a tray. The injectors inject
samples from position 1 first, followed by samples from positions 2 and 3. If the
two injectors do not have the same number of samples, the injector that
completes its sequence first remains idle while the other finishes.
You can mount two injectors onto the 6890, the 5890, and the 5880 GCs. You
cannot mount two injectors onto 5700 Series GCs.
