Portable pH/ISE allow the flexibility to perform an ISE measurement in labs with limited bench space and can be stored relatively easily. Two models are available including one dedicated to the fluoride measurement while the other can accept other ISEs and has the ion charge and weight pre-programmed for the specific parameter.
Benchtop pH/ISE meters include a two channel option in which a pH probe can be connected to one channel and the bromide ISE to the other. The benchtop meters have the ion charge and formula weight pre-programmed for use with the bromide ISE. The benchtop meters also have incremental methods pre-programmed, including the known addition, known subtraction, analyte addition, and analyte subtraction methods.
Electrodes & Probes
The cadmium ISE is a solid state electrode available as either a single half-cell or combination design that is complete with a reference cell. These electrodes incorporate a solid sensing surface.
Solutions for cadmium measurement include an ISE standard and ISA for calibration and measurement. Other solutions include the fill solution that is used with the ISE.
Accessories include halide polishing strips and magnetic stirrers to ensure adequate mixing when using an ISE.
