AutomaticQC Cartridge Fluidic Components

The AutomaticQC cartridge contains the following fluidic components:
• valve assembly
• QC material
• tubing
The valve assembly consists of a sliding valve, valve seal, valve lubricant,
and AutomaticQC probe.
The sliding valve is controlled by a stepper motor and a position detector
system that moves the valve and accurately positions it using two position
sensors. The valve has five positions, each of which enables one of the five
QC reagents to be pumped through the stainless steel probe in the center
of the valve. The probe remains stationary while the valve travels vertically
about the probe to change the hydraulic path between the AutomaticQC
cartridge and the measurement cartridge.
The QC material is supplied in five foil laminated bags, each of which holds
one of five levels of QC material. Each bag is firmly secured in place with
an inner and outer polystyrene clamp. Five nylon tubes, each of which
connects one of the five bags to the valve assembly, serve as flow paths for
the QC reagents.
