EXPRESS METHOD OF QUANTITATIVE DETERMINATION OF UREA IN MILK
Journal Title: Міжнародний науково-практичний журнал Товари і Ринки - Year 2017, Vol 1, Issue 24
Abstract
The proposed methodical approach in the variant of using the method of additives (MA) expects quantitive determination of urea in milk samples by spectrophotometric method without the need to build a calibration curve and long calculations. This allows significantly speed up the analysis process, reduce material and time costs and at the same time to obtain correct and accurate results, which is confirmed by the validation. The procedure is effective in the range of 0.14–0.7 mg/mL, the detection limit is 0.05 mg/mL. The uncertainty forecast was 7.33 %, which does not exceed the maximum allowable uncertainty of the technique (10 %).
