Abbott i-STAT Alinity - 1.8 - i-STAT Alinity Printer; Overview

Calibraon of the i-STAT Alinity instrument
The instrument houses the mechanical and electrical systems necessary to control uid movement
within the cartridge, control the temperature, measure barometric pressure, measure electrical signals
generated by the sensors, and display and transmit results. The instrument’s funcons are factory
calibrated to specicaons that are programmed into the instrument along with acceptability limits,
which, when exceeded, cause the instrument to display quality check messages, or to display *** rather
than results.
Abbo Point of Care developed the internal simulator that funcons as a signal-checking mechanism on
every cartridge inserted. The internal simulator is a combinaon of hardware and soware that tests the
ability of the instrument to accurately read sensor signals. The instrument performs an internal simulator
test on every cartridge run. The internal simulator simulates potenometric, amperometric, and
conducometric signals at three levels consistent with a range that includes very high and very low
concentraons of analytes. The simulaon is conducted depending upon the cartridge inserted to
perform this tesng. Therefore, the set of sensors on the inserted cartridge determines the signals
tested.
