Question
What is the detection limit for ISE/HS25Cl (E41M004)?
Summary
The typical detection limit is 2 x 10-6 M.
Answer
The detection limit is defined by the cross-section of the two extrapolated linear parts of the ion-selective calibration curve. In practice, detection limit on the order of 10-5-10-6M is measured for most of ion-selective electrodes. The observed detection limit is often governed by the presence of other interfering ions or impurities.
The concentration range goes from 1 x 10-6 to 1 M Cl- (0.04 to 35000 ppm).
The typical detection limit is 2 x 10-6 M.
