On-column injection mode
There are two injection modes: no (normal) and yes (on-column). Normal is
used with packed and split/splitless inlets. On-column mode is used with on-
column inlets and changes the carriage speed and the position over the inlet.
Figure 57. Switch for setting the on-column injection mode
Caution When you move the injector from one inlet to another, double-check the
injection mode. Be sure it is set to the correct injection mode. If you use the
wrong injection mode, you may damage the column, needle, and syringe. The
chemical performance of your GC may also suffer because the carriage speed
is slower.
