ISE Standards

ISE standards are used to calibrate ion selective electrode measurement systems by correlating the electrode output with the concentration of the analyte. Pairs of standards with concentrations that differ by a factor of ten (e.g. 1, 10, 100 or 1000 mg/L) are typically used, although other combinations may be used when a narrower analytical range is desired.
