  • METHOD AND DEVICE FOR DETECTING UREA
    Publication number: 20240094214
    Abstract: A method and device for detecting urea are provided. The method for detecting urea includes the following steps. A derivatization reagent reacts with a sample to obtain a mixture, wherein a reaction time period for reacting urea in the sample with the derivatization reagent to form a derivative product is controlled. The derivative product is separated from the mixture. The amount of separated derivative product is analyzed to determine the concentration of urea in the sample.
