The PVC membrane comprised with organic ion exchanger produces a potential change due to the nitrate ion exchange between the organic polymer membrane and the sample. The internal sensing elements are housed within a durable epoxy body.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eLiquid membrane sensor\u003c\/li\u003e \u003cli\u003eDetection from 0.62 to 6,200 mg\/L NO\u003csub\u003e3\u003c\/sub\u003e-\u003c\/li\u003e \u003cli\u003eFor use with HI-5315 reference half-cell\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eThe HI-4013 is a Nitrate half-cell Ion Selective Electrode (ISE).\u003c\/h3\u003e \u003cp\u003eThe nitrate Ion Selective Electrode is a potentiometric half-cell sensor housed within an epoxy body.\u003c\/p\u003e \u003cp\u003eThe internal elements are isolated from the sample by an organic polymer sensing membrane.

This liquid membrane sensor requires a separate reference electrode to complete the measurement system.\u003c\/p\u003e \u003cp\u003eHanna’s liquid membrane half-cell ISEs are designed for use with the HI-5315 reference half-cell. The reference half-cell features a cone style junction. The skirted cone geometry of the sensor 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 \u003cp\u003eFor the HI-4013 to measure nitrate accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the nitrate ionic strength adjuster (ISA) solution. The ISA ensures that the activity coefficient is constant so the concentration of free nitrate ions can be measured.\u003c\/p\u003e \u003cp\u003eMeasuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI-4013 nitrate liquid membrane ISE can measure from 10µM (0.62 mg\/L) to 0.1M (6,200 mg\/L).\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eParameter\u003c\/td\u003e\n\u003ctd\u003eNitrate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003ePolymer Membrane; Half-cell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Range\u003c\/td\u003e\n\u003ctd\u003e0.1M to 1X 10-5M 6200 to .62 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptimum pH Range\u003c\/td\u003e\n\u003ctd\u003e3.0 to 8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e0 to 40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApproximate Slope\u003c\/td\u003e\n\u003ctd\u003e-56\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody O.D.\u003c\/td\u003e\n\u003ctd\u003e12 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInsertion Length\u003c\/td\u003e\n\u003ctd\u003e120 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003ePVC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable\u003c\/td\u003e\n\u003ctd\u003e1m coaxial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector\u003c\/td\u003e\n\u003ctd\u003eBNC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePossible Applications\u003c\/td\u003e\n\u003ctd\u003eDetermination of free nitrate in natural waters (fresh and sea), and in emulsified food and plant samples\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640063074677,"sku":"HI-4013","price":1028.09,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/nitrate-ise-half-cell.jpg?v=1791580172","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-4013-nitrate-half-cell-ise","provider":"Test All Water","version":"1.0","type":"link"}
