With the ability to measure positive and negative ion concentrations and flexible adaptable methods that can be modified for either use in the lab or field
Ion selective electrodes have been widely used for a variety of applications for more than 30 years.
With the ability to measure positive and negative ion concentrations and flexible adaptable methods that can be modified for either use in the lab or field without interference from colour or turbidity.
Ideal for measuring ion concentration in water, food, pharmaceutical and biological samples.
Giving a simple and fast method of analysis, with an extensive library of methods to suit your application, saving time and money.
Relatively low cost to purchase and operate in comparison to alternative methods for ion analysis. Choose from three methods of determination to optimise your accuracy and reproducibility over a wide range of sample concentration.
Most commonly used is direct measurement, which is ideal for samples of similar background and is fast, giving a result in two to three minutes.
Incremental techniques such as known addition allows for some automation and is useful for high concentrations and samples with complex matrices needing no electrode calibration.
Alternatively use titration for an accurate, precise and automated end point measurement.
There are 28 Orion ion selective electrodes available, with combination or half cell and reference systems available for most ions.
Solid state electrodes can be used for fluoride, chloride, lead and silver/sulphide.
Plastic membrane electrodes are available for ammonium, calcium, chloride, potassium and nitrate.
Gas sensing versions are available for ammonia, oxygen and carbon dioxide.
