Errors in chemical sensor measurements

Abstract

Various types of errors during the measurements of ion-selective electrodes, ion-sensitive field effect transistors, and fibre optic chemical sensors are described. The errors were divided according to their nature and place of origin into chemical, instrumental and non-chemical. The influence of interfering ions, leakage of the membrane components, liquid junction potential as well as sensor wiring, ambient light and temperature is presented. © 2001 by MDPI.
