Instructions for Use

When performing measurement techniques such as direct measurement and incremental methods, ISEs require calibration to obtain accurate readings. Calibrating up to two points is recommended to improve accuracy. Volumetric glassware can be used to dilute the standard solution to the expected concentration of the sample to be measured. ISE calibration standards and sample solutions should always have the same ionic strength; before measurement, the exact volume of ionic strength adjuster (ISA) must be added to all standards and samples.
