Abstract
In this paper, we summarized flow injection analysis systems for determination of urea in the alcohol beverages. A lot of FIA methods based on the color-forming reactions without enzyme and detection of the hydrolysate of urea with urease were reported. Most of these methods were categorized as spectrophotometry (such as absorptiometry, fluorometry, luminometry), calorimetry, potentiometry and amperometry in combination with gas diffusion devices. The systems for determination of urea in serum, urine, and so on were also described.
