The photos below are examples of each type of Orion Ion-Selective Electrode. The design of the sensing element determines the sensitivity and selectivity for the ion of interest. Orion ISE's have been designed to provide you with the optimum in both performance and reliability.

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. Analytical methods using ISE's have been developed and published throughout the world.

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.  

SAVE TIME AND MONEY

Electrode measurements are simpler and faster than other analytical techniques. Time-consuming sample preparation steps such as filtrations and distillations are rarely needed. Analysis time is typically under one minute.

A direct readout meter displaying concentration in units of your choice is the fastest, easiest ISE measurement system. Orion ISE/pH meters display concentration in units of your choice, completing the 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. ISE's are inexpensive. Typically, the cost per test is only a few cents.
