electrode (ISE) in conjunction with a double-junction reference electrode, or a chloride
combination ISE, and a pH meter with an expanded millivolt scale or an ISE meter capable of being
calibrated directly in terms of chloride concentration.
2.2 Standards and samples are mixed 50:1 with an ionic strength adjustment solution
(ISA). Calibration is performed by analyzing a series of standards and plotting mV vs. chloride
concentration on semilog paper or by calibrating the ion meter directly in terms of chloride
concentration.详细>
