Description
ISA solution for halogen electrodes is a 500 ml ionic strength adjuster intended for use with halogen ion-selective electrodes. ISA solutions are used to dilute samples and calibration standards so that ionic activity is balanced across all solutions measured by the ISE method. They may also incorporate pH adjusters or substances that help protect against interferences, supporting consistent direct and incremental ISE determinations. Hanna Instruments offers a complete range of solutions for ISE electrodes; ISE standards are required for direct and incremental measurement and are available for a variety of ISE parameters with certificate of analysis. This halogen-electrode ISA preparation belongs to that accessory line and is supplied as one 500 ml unit for laboratory electrochemical work. Hazard classification includes H319 (causes serious eye irritation), signal word Warning, GHS07, with corresponding precautionary statements. Net weight is 0,66 kg and gross weight 1,66 kg. The solution supports standardised sample and standard preparation when working with halogen ISE systems.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about Ionic Strength Adjuster (ISA) for Halide ISEs
What is this article?
Ionic Strength Adjuster (ISA) for Halide ISEs is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Lab instruments.
A pH electrode is a glass membrane and a reference. It is a consumable: the glass ages, the junction clogs, and the reading drifts. A refillable electrode and a gel electrode differ in how they are maintained. The connector has to match the meter. The electrode, not the meter, is usually what is wrong.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
Which category should I open next?
The category is pH & electrochemistry. The sub-category is pH electrodes & sensors. The catalogue is Lab instruments.
