Measurement by
ion selective electrode (ISE) is applicable in virtually every laboratory.
Measure ion
concentrations in such samples as water, food, pharmaceuticals, and biological
samples. The main advantages of electrode technology are the variety of
analytical methods available. Choice of measurement method improves accuracy
and reproducibility of results. Direct calibration is the most commonly used
electrode method. Sample concentration is directly read on a specific ion
meter or from a calibration curve. Incremental methods increase the number of
measurable species. With these methods, electrode calibration is unnecessary,
making them useful when measuring complex samples. Electrodes can also be used
as end point detectors in titrations. Electrode measurements are simpler and
faster than other analytical techniques. Time-consuming sample preparation
steps such as filtrations and distillations are rarely needed. A direct
readout meter displaying concentration in units of your choice is the fastest,
easiest ISE measurement system. In comparison to other methods, such as AA or
ion chromatography, the initial cost of setup is less and does not require
additional expensive readout equipment. Methods are adaptable to both lab and
field use. Sample color or turbidity does not affect the measurement. ISEs
are inexpensive. Typically, the cost per test is only a few cents. The design
of the sensing element determines the sensitivity and selectivity for the ion
of interest. Orion ISEs have been designed to provide you with the optimum in
performance and reliability. All electrodes have 1m cables.
