Checking your work
❐ Be sure the mounting pin is seated in the hole of the disk. The injector’s feet
should touch the mounting bracket. Be sure the gas lines are not routed
under the feet or the mounting pin.
❐ Turn the turret so you can see the inlet of the GC, and open the door to the
syringe. Be sure the inlet is flush with the surface of the hole in the injector’s
base. This check does not apply to on-column inlets.
❐ If your system does not include a tray, read “Placing sample vials in the
standard injector turret” in chapter 2.
For information on installing syringes, see “Selecting and installing syringes” in
chapter 2. See this section for instructions on how to align the syringe to the
inlet. Alignment is critical when injecting onto a 320- or 250-µm column.
Chapter 6, “Special Topics,” contains more information on use of 320- and
250-µm columns.
Installing the tray
The tray delivers samples to one or two injectors depending on the
configuration of the gas chromatography system. The arm and gripper
mechanism in the center of the tray loads sample vials into the injector turret
and then returns them to the tray after each injection. It can also transport
sample vials to and from the G1296A/G1926A bar code reader.
Each of the four removable tray quadrants holds 25 vials. Each is hollow and
has fittings so that you can circulate a temperature-controlled fluid through it.
