Quality Management
This section describes the functionalities that the analyzer, apart from the built-
in quality checks, applies to ensure the measurement quality.
System checks:
System checks are performed regularly and automatically consist of the
following checks:
 Communication checks
(to check the communication between the PC and embedded systems. Are
performed after analyzer startup.)
 Software checks
(to check the correct Data Management system (DMS) against the correct wet
section software. Are performed after analyzer startup.)
 Mechanical checks
(to check the calibration and the positioning of the flow selector and the
solution pump volume and to check for leakages. Solution pump volume and
leakage checks are performed once a day. Flow selector calibration checks are
performed with every activity)
 Electronical checks
(to check the wet section liquid transport, leak current and liquid sensor. Are
performed once a day.)
 Temperature checks
(to check the sensor array, spectrophotometer and the temperature inside the
analyzer. Are performed continuously.)
 Consumable integrity checks on time of installation
(Sensor cassette: To check the expiration date, lifetime, conditioning time and
sensitivity of all the parameters. The activities mentioned under analysis
check are also checked. These checks are performed after sensor cassette
installation.
Solution pack: To check the expiration date, lifetime and number of remaining
tests along with the correct solution pack positioning and sample flow
integrity. These checks are performed after solution pack installation.)
Analysis checks:
Analysis checks are performed in connection with analysis – be it patient sample
analysis, calibration or a QC measurement – consist of the following checks:
 Status calibrations/checks
(to check the status of the sensors a status calibration is performed on all the
sensors except on the pO
2
, where is status check is performed. A detailed
description of the calibrations can be found further on in this chapter under
the individual sensor types.)
 Sample integrity checks
(to check for sensor response stability, air bubbles, insufficient sample volume
and sample path obstructions. Blockages can indirect be revealed during these
checks.)
 Temperature checks
(to check the sensor array, spectrophotometer and the temperature inside the
analyzer. Are performed continuously and with every measurement.)
 Mechanical checks
(to check the pressure, solution pump and flow selector and to check for
leakages.)
