5. Sensors and optical system ABL90 FLEX reference manual Overview General construction Sensors In this manual, the term sensor refers to an individual sensor as part of the sensing array within a sensor cassette. The electrical signal from each sensor is measured by proprietary analog electronics contained within the analyzer unit.
ABL90 FLEX reference manual 5. Sensors and optical system General measuring principles Introduction There are four different measuring principles employed in the sensors in the ABL90 FLEX analyzer. Potentiometry: The potential of a sensor chain is recorded using a voltmeter, and related to the concentration of the sample (the Nernst equation).

ABL90 FLEX reference manual 5. Sensors and optical system General information Definition Calibration is the process that relates the electrode signals during the calibration sequence to the values of the calibrating solutions and air. Calibration enables the electrode signals to be converted to the accurate values for an unknown sample.
5. Sensors and optical system ABL90 FLEX reference manual The calibration equation Definition The calibration equation expresses the relationship between the electrical measurement at a sensor and the concentration of the substrate specific to the sensor. The calibration line forms the basis of the scale used by the analyzer to convert electrical measurements to concentrations.
ABL90 FLEX reference manual 5. Sensors and optical system Sensitivity Definition The electrode sensitivity illustrates the slope of the calibration line compared to the slope of the theoretical electrode. The sensitivity of the theoretical electrode is 100 % or 1.00.
5. Sensors and optical system ABL90 FLEX reference manual Measurement Sample A blood sample gives a potential reading of 4.8 mV at the pH sensor. Reading measurements off from the calibration line shown below, this potential corresponds to a pH of 7.35.

ABL90 FLEX reference manual General information This appendix includes general information about quality control/quality management that is relevant and in some case also specific for the ABL90 FLEX analyzer. Some of the sections in this appendix contain information about both built-in and manual quality controls.

Page 316
ABL90 FLEX reference manual User control ranges (for manual QC only) Introduction The specified control ranges in the inserts, which are established by Radiometer, include all well-functioning analyzers, and the uncertainty budget will therefore include a contribution derived from the analyzer-to-analyzer variation. This means that results obtained on one specific analyzer should fall within control ranges that are narrower than the insert control ranges.

where = higher values, and = lower values. Radiometer recommends that ampoules that have been stored in a cool place are conditioned at a known room temperature for at least 5 hours before a measurement, and we strongly advise not to keep ampoules on the top of an analyzer as the temperature there can vary.

Appendix – Quality control ABL90 FLEX reference manual Westgard rules About The Westgard rules are a set of statistical rules that, when applied to the quality Westgard rules control results, can aid the following: Increase the probability of detecting an error on the analyzer by analyzing the quality control measurements ...
ABL90 FLEX reference manual Appendix – Quality control Rule 1 This rule is a warning rule. Measurement value is outside the mean 2 SD. Corrective action: Perform another measurement on a new ampoule of the same level. If the second result falls within the control range, then the first result can be attributed to normal statistical variation.
Appendix – Quality control ABL90 FLEX reference manual Rule R This rule is a rejection rule. The difference between two consecutive measurements exceeds 4 This indicates inconsistency in your procedures or an unstable analyzer. Corrective action: Perform steps described in section Quality control evaluation further in this appendix.
(Each QC ampoule must be used immediately after being opened, for one measurement on one analyzer only, in order to ensure the reliability of the measurement). Did you use Radiometer QUALICHECK adapter? If own user-defined limits were entered: Did you enter too narrow control ranges? If everything is OK –...

ABL90 FLEX reference manual Appendix – Traceability to the primary standards at Radiometer Traceability The primary pH standards are traceable to the definitive method for pH. The definitive method is based on a Hydrogen Electrode System. The primary pH standards are obtained from the Danish primary laboratory for Electrochemistry (DPLEC) at the Danish Institute of Fundamental Metrology (DFM).
Appendix – Traceability to the primary standards at Radiometer ABL90 FLEX reference manual The primary standards used are the so-called Ca transfer standards, produced ® from CaCO Urtitersubstanz , produced by Merck. The transfer standards are pH-stabilized to pH = 7.4, with 1 mmol/L HEPES and an ionic strength of 160.0 mmol per kg.
