Measurement
A blood sample gives a potential reading of 4.8 mV at the pH sensor. Reading
off from the calibration line shown below, this potential corresponds to a pH of
7.35.
To compensate for deviations from ideal behavior (ex. dilution of sample with
residual rinse solution, and change in gas level by contact with the sample
path), a correction is applied, to give the final value.
The correction is typically a linear correction, and is described for each sensor
type in the following.
