What is the detection limit for ISE25F (E41M007)?
The estimated detection limit is 10 -6 M.
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 is: 5 x 10 -6 to 1 M F- (0.01 to 20000 ppm)
The estimated detection limit is: 10 -6 M.
