QIAsymphony SP/AS Consolidated Operating Guide 12/2017 15212.5.1 Inventory scan of “Eluate and Reagents” drawerThe inventory scan of the “Eluate and Reagents” drawer consists of the following steps in thefollowing order:1. Bar codes of slots 1–3 or bar codes of adapters on slots 1–3 are scanned.ImportantFor a particular slot, either the bar code of the slot is scanned or, if an adapter ispresent 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 adaptertype is present on a particular slot.If the expected and current statuses of the slots/adapters do not match, a message will appear toprompt the user to correct the problem.ImportantThe QIAsymphony AS is not able to identify the type of consumables on theadapter. It is therefore important that the correct plates/tubes are loaded on theadapters, 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 andthat 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 categorizedas full. If the first or last tip is missing, a full scan will be performed to determine the number oftips in the tip rack. If there are not enough filter-tips of the correct type available, a message will appear on thetouchscreen prompting the user to load more tips.ImportantIf there are insufficient tips available for the defined assay run and it is notpossible to load more tips before starting the run, tips can be reloaded duringthe assay run. This will be documented in the loading information file, and in theresult file if user interaction was required.Pausing the run to reload tips will result in the samples being flagged as“unclear”.
