These high quality reagents follow an adaptation of the EPA method 365.2 and Standard Methods for the Examination of Water and Wastewater, 20th edition, 4500-P E, ascorbic acid method. In this method, the reaction between orthophosphate and the reagent causes a blue tint in the sample. The amount of phosphorus is then measured colorimetrically. The intensity of colour is determined by a compatible photometer and the concentration is displayed in mg\/L (ppm) of phosphorus. These reagents are designed to be used with samples that have an expected range of 0.00 to 1.60 mg\/L (ppm) phosphorus.\u003c\/p\u003e \u003ch3\u003ePre-dosed reagents\u003c\/h3\u003e \u003cp\u003eHanna vials contain pre-dosed reagent so the user simply needs to add a small quantity of the sample to the vial followed by heating 30 minutes at 150°C and cooling, then the addition of the NaOH solution to use as the blank, followed by the addition of the phosphorus powder reagent to measure the concentration. With pre-dosed vials, test preparation time is dramatically reduced and there is no time-consuming reagent preparation procedure or glassware cleaning. The vials and caps of the reagents have been designed to avoid accidental reagent spills. Due to the pre-dosed reagents, the amount of chemicals and handling time is also minimised. These vials feature Hanna’s barcode recognition system exclusive to the HI-83224 Wastewater Treatment benchtop photometer. The meter scans each vial to automatically identify sample method and range. The barcode has four digits: the first two digits are for parameter identification and the second two digits are for reagent lot ID. Vials for different methods can be distinguished by a barcode printed on the vial and the cap colour.\u003c\/p\u003e \u003cp\u003e\u003ci\u003e*This reagent uses the Ascorbic acid method\u003c\/i\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640101183861,"sku":"HI-94758B-50","price":166.34,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/phosphorus-acid-hydrolyzable-ascorbic-acid-method-with-bar-cod.jpg?v=1791581317","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-94758b-50-phosphorus-reagent-acid-hydrolyzable-ascorbic-acid-method-with-bar-code","provider":"Test All Water","version":"1.0","type":"link"}
