1. The process, product features and biuret control in production of high analysis urea-based compound fertilizer are described, with the slow release ability of the product discussed.

2. The liquid ammonia with oil can produced biuret scale on the urea system in chemical fertilizer plant. The efficiency of heat exchanger and producing capacity of urea were reduced.

3. Methods Biuret method was used to measure the TP with different concentration of bilirubin. Results TP with adding bilirubin in serum was higher than TP without adding bilirubin in serum.

4. The analysis method for biuret content in long-efficacy urea using hydroquinone as an additive is studied and tested.

5. Method Uusing biuret colorimetry to determine the content of protein which had been precipitated by trichloroacetic acid.

6. Objective To establish a kind of rapid and simple biuret method for measuring cerebrospinal fluid protein of automatic analyser.

7. Total solvable peptide content in the fermented fishmeal was determined by using the biuret method, and polypeptide in the precipitate by using Kjeldahl method.

8. A kind of two-component waterborne polyurethane(2K-WPU) was prepared by mixing HDI biuret and water-soluble acrylic resin, a dilution with water being followed.

9. Methods The precision, recovery rate, the examination limit, the linear scope and the interference experiments were done by improving biuret reagent in order to ensure the method's basic function.

10. Objective For conquering the interference of lipid turbidity, jaundice and hemolysis, changed simple reagent of biuret to double reagent (the method).

11. In order to ensure the efficacy of animal polypeptide on clinic, the purified animal polypeptide was analyzed by polyacrylamide gel electrophoresis, and its content was determined by biuret test.

12. Method U. S Standardization Com mission's standard file EP10-T2 was used to select representative ALT and TP. AL T was determined with the enzyme reaction, TP was determined with biuret reaction .

12. Wish you will love and make progress everyday!

13. However these troubles of concentrated urea liquor crystallizing and blocking pipe, as well as urea changing into biuret at high temperature should be avoided.

14. In the research, I analyzed the influence on crops caused by different biuret concentrations in compound fertilizers, using pattern of solution culture and potted.

15. Platelet aggregation was measured turbimetrically and plasma fibrinogen level was determined by biuret method.

16. Methods for the modification of isocyanates include process of urethane, dimerization, trimerization, biuret, carbodiimide, and blocking reaction, etc.

17. A reversed - phase HPLC method was established to determine the biuret content in urea.

18. A method of measurement of the content of Insulin in transmucosal pharmaceutics was established by biuret test.

19. Its ninhydrin reaction was negative, but after acid hydrolysis, its ninhydrin reaction and biuret reaction were positive.

20. A two-component waterborne polyurethane(2K-WPU) was prepared by mixing water soluble acrylic resin and HDI biuret, and then diluting it to phase inversion with water.
