Without addition of ISA, an Ion Selective Electrode measures ion activity. Addition of ISA stabilises the ionic strength and permits measurements as ion concentration. With some ISEs, the ISA solution is also used to adjust the solution’s pH or to remove any potential interference from competing ions present.\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640063664501,"sku":"HI-4016-00","price":55.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/sodium-isa-solution.jpg?v=1791580193","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-4016-00-sodium-isa-solution","provider":"Test All Water","version":"1.0","type":"link"}
