The assay does not involve any enzyme, the reaction is a chemical \/ colorimetric reaction (therefore it belongs ot the product line Enzytec™ Color).\u003cbr\u003e\r\n\u003cbr\u003e\r\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\r\n\u003cul\u003e \u003cbr\u003e\r\n\u003cli\u003eTest format: 2 x 80 ml R1 reagent + 1 x 25 ml R2 reagent (100 assays)\u003c\/li\u003e\r\n\u003cbr\u003e\r\n\u003cli\u003eSample preparation: Wine samples are tested directly\u003c\/li\u003e\r\n\u003cbr\u003e\r\n\u003cli\u003eIncubation time: 10 minutes\u003c\/li\u003e\r\n\u003cbr\u003e\r\n\u003cli\u003eValidated matrices: Wine and must\u003c\/li\u003e\r\n\u003cbr\u003e\r\n\u003cli\u003eDetection range: 0.2 - 4 g\/L Tartaric acid\u003c\/li\u003e\r\n\u003cbr\u003e\r\n\u003cli\u003eDetected analyte: Tartaric acid\u003c\/li\u003e\r\n\u003cbr\u003e\r\n\u003cli\u003eEvaluation: Colorimetric assay (520 nm)\u003c\/li\u003e\r\n\u003cbr\u003e\r\n\u003cli\u003eRelated products: Enzytec™ Color Copper (en)|Enzytec™ Color Iron (en)\u003c\/li\u003e\r\n\u003c\/ul\u003e\u003cbr\u003e\r\n\r\n\u003ch3\u003eGeneral Information:\u003c\/h3\u003e\r\n\u003cbr\u003e\r\nThe determination of the Tartaric acid concentration is important for the wine industry and belongs to the range of colorimetric tests performed in analysis of wine as the determination of Iron, SO2-free, SO2-total and Copper. These tests are based on the use of chromogens, without any enzyme involved in the reaction.\r\n\r\n\u003cbr\u003e\u003cbr\u003e\r\n\r\nThe test principle is that, under acidic conditions, Tartaric acid (or tartrate) reacts with a Vanadium salt and produces a colored complex (metapervanadyl tartrate). The amount of this chromogen is stoichiometrically related to the amount of tartrate present in the sample. It is measured on a spectrophotometer at 520 nm. \u003cbr\u003e\u003cbr\u003e\r\n\r\n\u003ch3\u003eBenefits:\u003c\/h3\u003e\r\n\r\n\u003cul\u003e\r\n\r\n  \u003cli\u003e\n\u003cstrong\u003eEasy:\u003c\/strong\u003e Principle of photometric test; without special sample preparation; without additional laboratory equipment.\u003c\/li\u003e\r\n\r\n  \u003cli\u003e\n\u003cstrong\u003eFast:\u003c\/strong\u003e Results after 10 minutes reaction time.\u003c\/li\u003e\r\n\r\n  \u003cli\u003e\n\u003cstrong\u003eFavorable:\u003c\/strong\u003e Savings compared to conventional methods of analysis.\u003c\/li\u003e\r\n\r\n  \u003cli\u003e\n\u003cstrong\u003eReliable:\u003c\/strong\u003e High correlation between photometric and fluorometric methods.\u003c\/li\u003e\r\n\r\n\u003c\/ul\u003e","brand":"R-Biopharm","offers":[{"title":"Default Title","offer_id":48119538286883,"sku":"RBIOE3100","price":134.7,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/5896\/9012\/files\/E3100.jpg?v=1792114814","url":"https:\/\/onelab.co.nz\/products\/enzytec%e2%84%a2-color-tartaric-acid","provider":"Onelab","version":"1.0","type":"link"}
