Hanna ISA solutions are formulated to fix the ionic strength of a sample and standards so that they are both constant. Without addition of ISA,  an ion selective electrode would measure ion activity; addition of ISA stabilizes 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 interferences from competing ions that are present.\u003c\/p\u003e\n\u003ch5\u003eAir tight bottle with tamper-proof seal\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eEnsures quality and freshness of solution\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch5\u003eEach bottle marked with lot number and expiration date\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eHanna ISE standard solutions are specially formulated to have an expiration of 5 years from manufacture for an unopened bottle\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch5\u003eImportance of ISA*\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eFixes a solution's ion activity to be constant so concentration can be determined\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAdjusts the pH of a solution required for some ISEs\u003c\/li\u003e\n\u003cli\u003eComplexes interfering ions in a sample to allow measurement of free ions of interest\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e* If an ISA solution is used with a sample,  then it must be used with the calibration standards in equal proportions.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI4012-00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Ionic Strength Adjuster (ISA) for Lead\/Sulfate ISEs - HI4012-00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertificate of Analysis\u003c\/td\u003e\n\u003ctd\u003e No\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e bottles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003e 500 mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca target=\"_blank\" href=\"https:\/\/manuals.hannainst.com\/HI4012-00\"\u003eIonic Strength Adjuster (ISA) for Lead\/Sulfate ISEs - HI4012-00\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871287705969,"sku":"HI4012-00","price":10362.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi4012-00_1.jpg?v=1792646070","url":"https:\/\/hannainst.in\/products\/ionic-strength-adjuster-isa-for-lead-sulfate-ises-hi4012-00","provider":"hanna","version":"1.0","type":"link"}
