Portable pH/ISE allow the flexibility to perform an ISE measurement with a portable meter even though the ISE measurement method is more suitable to a benchtop environment due to the addition of the ISA for fixing the ionic strength and the use of a magnetic stirrer to keep the sample homogenous. The portable pH/ISE meter has the ion charge and formula weight pre-programmed for concentration measurements.
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 bromide ISE is a solid state electrode and is available as either a single half-cell or combination design that is complete with a reference cell. These electrodes incorporate a solid sensing surface made of compressed silver bromide.
Solutions for bromide measurement include an ISE standard and ISA for calibration and measurement. Other solutions include the fill solution that is used with the ISE.
