8.5.2 Loading the plate carrier
The plate carrier can also be used for sample input. For more information, refer to the
QIAsymphony SP/AS User Manual — General Description . If you intend to use the plate carrier,
contact QIAGEN Technical Services
8.6 Performing inventory scans (SP)
An inventory scan of each drawer of the QIAsymphony SP must be performed before a sample
preparation protocol can be run. The QIAsymphony SP uses a laser to check the type and number
of consumables, and the type and location of adapters loaded in each drawer. A bar code
detection system recognizes and scans 1D or 2D bar codes (e.g., on the reagent cartridge). The
laser and bar code camera are integrated in the robotic arm. This ensures that positions over the
whole worktable can be scanned. The inventory scan is drawer-specific. This means that only the
drawer that has been opened will be scanned for changes.
8.6.1 Inventory scan of the “Reagents and Consumables” drawer
The inventory scan of the “Reagents and Consumables” drawer is divided into 2 main parts, each
with several subparts.
Laser scan — reagent cartridge
Reagent cartridge slots are scanned. The instrument will check first for sealed troughs in the
respective reagent cartridge.
Important
The inventory scan is not able to detect whether the piercing lid is in place on
top of the reagent cartridge or not. If the piercing lid is missing, the
QIAsymphony SP will detect an error during first use of the reagent cartridge
and processing of the corresponding sample batch will be canceled.
Important
Ensure that all 2D bar codes are accessible by the sensor.
2D bar codes on reagent troughs, the magnetic-particle trough, and the enzyme rack are
checked. In addition, the piercing status of the reagent cartridge is checked.
