Full Description

ISEs require calibration for accurate readings. Calibration of up to two points is recommended for enhanced accuracy. ISE calibration standards and sample solutions should always have the same ionic strength; the exact volume of ionic strength adjuster (ISA) must be added to all standards and samples prior to measurement.
