The conditioning of the electrode is a two-step process in which the glass is etched then rehydrated. The first step is etching. This process removes a thin layer of sensitive glass from the sodium membrane, exposing a sodium-containing fresh surface. The second step is rehydration in which the probe is placed in storage solution to rehydrate the glass membrane. Allowing the glass to rehydrate after etching provides optimum conditions for the exchange of sodium ions between the membrane and solution.\u003c\/p\u003e\n\u003cp\u003eFor the FC300B to measure sodium accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the sodium ionic strength adjuster (ISA) solution. The sodium ISA is important for two reasons. One is that the ISA buffers the pH of the standard and sample to above pH 9.8. This removes any interference from hydrogen ions that occur at lower pH's. The second purpose of the ISA is to ensure that the activity coefficient is constant so the concentration of free sodium ions can be measured. Having solutions with a constant ionic strength reduces the margin of error between measurements of different samples at different concentrations.\u003c\/p\u003e\n\u003cp\u003eThe FC300B sodium glass ISE can measure from 10µM (0.23 mg\/L) to 1M (22, 990 mg\/L).\u003c\/p\u003e\n\u003ch2\u003eConversion Table for Na\u003csup\u003e+\u003c\/sup\u003e and NaCl\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x: auto; margin: 0 0 32px;\"\u003e\u003ctable rules=\"all\"\u003e\n\u003ccolgroup\u003e \u003ccol width=\"437\"\u003e \u003ccol width=\"171\"\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) Na\u003csup\u003e+\u003c\/sup\u003e to ppm (mg\/L) Na\u003csup\u003e+\u003c\/sup\u003e\n\u003c\/td\u003e\n\u003ctd\u003e22990\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eppm (mg\/L) Na\u003csup\u003e+\u003c\/sup\u003e to M (moles\/L) Na\u003csup\u003e+\u003c\/sup\u003e\n\u003c\/td\u003e\n\u003ctd\u003e4.35 x 10\u003csup\u003e-5\u003c\/sup\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eppm (mg\/L) Na\u003csup\u003e+\u003c\/sup\u003e to ppm (mg\/L) NaCl\u003c\/td\u003e\n\u003ctd\u003e2.54197\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eppm (mg\/L) NaCl to ppm (mg\/L) Na\u003csup\u003e+\u003c\/sup\u003e\n\u003c\/td\u003e\n\u003ctd\u003e0.39339\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\u003eSpherical Glass Tip\u003c\/strong\u003e - The spherical shaped tip design allows for a wide area of contact with the sample, permitting a faster electrode response with a higher degree of stability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGlass Electrode Body\u003c\/strong\u003e - The glass electrode body is suitable for a wide range of applications due to its chemical resistance.

The selective glass membrane blown on the tip of the sensor exchanges ions with the solution being measured. The charge imbalance between the membrane surface and internal cell of the sensor produces a voltage that changes in response to the sample's ion activity. 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\u003eFC300B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003eSodium Combination Ion Selective Electrode (ISE) - FC300B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Range\u003c\/td\u003e\n\u003ctd\u003eSodium (Na\u003csup\u003e+\u003c\/sup\u003e) 1.0M to 1 x 10-5M, 22,990 to 0.23 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\u003eglass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptimum pH Range\u003c\/td\u003e\n\u003ctd\u003epH 9.75 to 14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Length\/Overall Length\u003c\/td\u003e\n\u003ctd\u003eOverall: 120 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: +57\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\/FC300B\" target=\"_blank\" rel=\"noopener\"\u003eSodium Combination Ion Selective Electrode (ISE) - FC300B\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871187829105,"sku":"FC300B","price":45785.25,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/fc300_1200.jpg?v=1792645845","url":"https:\/\/hannainst.in\/products\/sodium-combination-ion-selective-electrode-ise-fc300b","provider":"hanna","version":"1.0","type":"link"}
