1) Classification
Divided into four types from the diaphragm: gas sensing electrode, solid-state electrode,
Glass electrode, ion exchange electrode.
2) Can test up to ten types of ions
For example: Br, Cd+, Ca2+, Cl -, Cu2+, F -, I -, Pb2+, Mn -, K+,
Na+, Ag+ , S2-, SCN-, NH3, NO3-

Eight ISE testing methods

Direct testing method: Using one to two points for calibration within a linear range and six points for calibration throughout the entire range to establish a calibration curve is an optimal standard method.
Known addition method: for high concentration and variable concentration samples
Sample addition method: for samples with high ion concentration
Blank value correction: a special method used for low concentration testing.
Sample reduction method: For samples that can only be indirectly tested, add some sample or standard solution to the sample until the potential changes to a certain value. Enter the added volume, and the pMX3000 (old instrument) will automatically calculate the ion concentration of the sample.
Known addition method for secondary addition: an optimal way to test samples with high ion concentration or different temperatures.
Known reduction method: The test ion reacts with the standard solution to form a precipitate or complex, which can replace the complex titration process.
