PerkinElmer OilExpress 4, User Manual

Page: 35 / 152

Overview of the OilExpress 4 System . 35
Both sample racks are arranged in columns of eight samples. Samples within a rack are
analyzed column-by-column from the top-right to the bottom-left of the rack (as viewed from
the front of the autosampler).
The allowed arrangement of sample racks (and also of tip boxes) on the deck is predefined
for your combination of autosampler, System Purpose (oil analysis by FT-IR, or FT-IR and oil
dilution) and Rack Type. The sample racks require a locating plate to be installed on the
autosampler deck.
OilExpress can also be configured to support other sample racks in some cases. This requires
support from PerkinElmer engineering to create adaptor plates and labware files, as well as
service support to configure a custom layout for the autosampler. For more information on
setting up a custom layout, consult your PerkinElmer Product Specialist or Service
Representative.
96-position (17 mm test tubes) rack
There are 96-position racks available for both 16 mm and 17 mm polypropylene tubes
(Figure 9). The start and end of each column on the rack is numbered, indicating the order in
which the tubes will be sampled when the rack is positioned on the deck.
