12.5.1 Inventory scan of “Eluate and Reagents” drawer
The inventory scan of the “Eluate and Reagents” drawer consists of the following steps in the
following order:
1. Bar codes of slots 1–3 or bar codes of adapters on slots 1–3 are scanned.
Important
For a particular slot, either the bar code of the slot is scanned or, if an adapter is
present on the slot, the bar code of the adapter is scanned.

Bar codes of slots 1–3 are scanned to determine whether the slots are empty or occupied.

Bar codes of adapters on slots 1–3 are scanned to determine whether a particular adapter
type is present on a particular slot.
If the expected and current statuses of the slots/adapters do not match, a message will appear to
prompt the user to correct the problem.
Important
The QIAsymphony AS is not able to identify the type of consumables on the
adapter. It is therefore important that the correct plates/tubes are loaded on the
adapters, as defined in the software.
2. Tip rack slots are scanned.

The disposable filter-tips are scanned to ensure that the correct tip type has been loaded and
that there are sufficient filter-tips available for the defined assay run.

If a tip is detected in the first and last position of the tip rack, the tip rack will be categorized
as full. If the first or last tip is missing, a full scan will be performed to determine the number of
tips in the tip rack.

If there are not enough filter-tips of the correct type available, a message will appear on the
touchscreen prompting the user to load more tips.
Important
If there are insufficient tips available for the defined assay run and it is not
possible to load more tips before starting the run, tips can be reloaded during
the assay run. This will be documented in the loading information file, and in the
result file if user interaction was required.
Pausing the run to reload tips will result in the samples being flagged as
“unclear”.
