Labware Configurations
NOTE: The allowed labware configurations are the same for single-spectrometer and DUO
(dual-spectrometer) systems.
The positioning of labware – injection station, sample racks, clean tip boxes and used tip
boxes – on the autosampler deck is critical for the safe operation of your autosampler. The
allowed configurations, known as Deck Layouts, depend on the system you have purchased
and the type of sample rack you are using. The Deck Layout defines the order in which
samples will be aspirated or in which tip boxes will be used when running analyses using the
OilExpress 4 software.
CAUTION
The OilExpress 4 software cannot sense the location of labware on the
deck, so incorrect positioning may lead to a collision that could cause
damage to your autosampler.
Ensure that you refer to the appropriate Deck Layout information in the
OilExpress 4 on-screen Help before starting an analysis.
The Deck Layouts are arranged to minimize the risk of contaminating samples or clean tips in
the unlikely event of a drip from a tip. All sample analyses run from the top-right to the
bottom-left of the deck and, within each sample rack, from the top-right to the bottom-left of
the rack. By sampling in this way, disposable tips containing aspirated oil samples will not
travel over unmeasured samples on the autosampler deck.
Figure 7 shows the correct positioning of sample racks (on the left deck) and tip boxes (on
the right deck) for the 96-position rack on an OilExpress 4 XL System (FT-IR-Only mode).
The used tip boxes are shown in the darker shade. The injection station is also shown at the
far right.
