{"product_id":"cyanide-half-cell-ion-selective-electrode-ise-hi4009","title":"Cyanide Half-Cell Ion-Selective Electrode (ISE) - HI4009","description":"\u003cp\u003eHanna's solid state half-cell ISEs are designed for use with the HI5315 reference half-cell. The reference half-cell features a cone style junction. The skirted cone geometry of the reference forms the liquid junction with the test solution at the tip of the junction cone, producing a highly stable reference potential and consistent flow rates of electrolyte into the solution. A simple press of the top portion of the ISE makes it easy to empty the electrolyte fill solution and replace when necessary.\u003c\/p\u003e\n\u003cp\u003eFor the HI4009 to measure cyanide accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the cyanide ionic strength adjuster (ISA) solution. The alkaline ISA ensures that the activity coefficient is constant so the concentration of free cyanide ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI4009 cyanide solid state ISE can measure from 1µM (0.026 mg\/L) to 0.01M (260 mg\/L).\u003c\/p\u003e\n\u003cp\u003eConversion Table for CN\u003csup\u003e-\u003c\/sup\u003e\u003c\/p\u003e\n\u003cdiv style=\"overflow-x: auto; margin: 0 0 32px;\"\u003e\u003ctable\u003e\n\u003ccolgroup\u003e \u003ccol width=\"220\"\u003e \u003ccol width=\"*\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003eMultiply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003emoles\/L (M) to ppm (mg\/L)\u003c\/td\u003e\n\u003ctd\u003e2.602 x 10\u003csup\u003e4\u003c\/sup\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eppm (mg\/L) to M (moles\/L)\u003c\/td\u003e\n\u003ctd\u003e3.843 x 10\u003csup\u003e-5\u003c\/sup\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003ch2\u003eFeatures at-a-glance\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eFixed Sensing Modules\u003c\/strong\u003e - Solid state half-cell ISEs are electrodes that detect free ions in a solution.

An equilibrium occurs due to the highly limited solubility of the membrane material in the sample. When the ionic strength of the solution is fixed by the addition of ISA, the voltage is proportional to the concentration of free ions in solution.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eHI4009\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003eCyanide Half-Cell Ion-Selective Electrode (ISE) - HI4009\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription\u003c\/td\u003e\n\u003ctd\u003esolid state; half-cell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Range\u003c\/td\u003e\n\u003ctd\u003eCyanide (CN\u003csup\u003e-\u003c\/sup\u003e) 0.01M to 1 10\u003csup\u003e-6\u003c\/sup\u003eM, 260 to 0.026 mg\/L (ppm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e0 to 80 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003eepoxy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptimum pH Range\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; pH 11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Length\/Overall Length\u003c\/td\u003e\n\u003ctd\u003e120 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Diameter\u003c\/td\u003e\n\u003ctd\u003e12 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable\u003c\/td\u003e\n\u003ctd\u003ecoaxial; 1 m (3.3’)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector Type\u003c\/td\u003e\n\u003ctd\u003eBNC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNotes\u003c\/td\u003e\n\u003ctd\u003eApproximate Slope -56 mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca href=\"https:\/\/manuals.hannainst.com\/HI4009\" target=\"_blank\" rel=\"noopener\"\u003eCyanide Half-Cell Ion-Selective Electrode (ISE) - HI4009\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871285412209,"sku":"HI4009","price":98941.5,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi4009_2016.jpg?v=1792646060","url":"https:\/\/hannainst.in\/products\/cyanide-half-cell-ion-selective-electrode-ise-hi4009","provider":"hanna","version":"1.0","type":"link"}
