Heated Zones identify the type of device installed in each of the heated
zones of the 3800, the upper temperature limit of these devices, their location
and what type of coolant, if any, the device uses. Column oven always
occupies one heated zone. The other available heated zones are numbered
1 through 6 and can be occupied by one of the following devices: 1079
injector, 1041 injector, 1061 injector, SPT, FID, TCD, ECD, TSD, PFPD,
Micro-TCD, large valve oven, small valve oven, or methanizer. SPT is
allowed only in zone 3.
The location typically refers to whether the device is installed in the front,
middle, or rear position on the top of the 3800. In the case of detectors the
location also refers to the relative positions of the detector electrometers
installed on the main electronics board. By default, zones 1, 2, and 3 are
identified as front, middle, and rear and zones 4, 5, and 6 are identified as
front, middle, and rear. Zones 1, 2 and 3 are normally used for injectors and
zones 4, 5, and 6 are normally used for detectors.
The temperature limit for all zones defaults to 450°C but can be set to a lower
value. The coolant choices are None, LN
2
, or LCO
2
. Note that zones 4 - 6
cannot be used with coolant.
The following screen shows an example of a configuration screen for the
3800 heated zones. This instrument is configured with two 1079 injectors,
both of which have an LCO
2
coolant option, and two FIDs.
