Automatic reducing sugar tester is an analytical instrument commonly used in food, beverage, biological products and other fields, which can quickly and accurately detect the reducing sugar content in samples. This article will introduce in detail the detection principle, operation steps, advantages and precautions of the automatic reducing sugar tester.
1. The detection principle of automatic reducing sugar tester.
The automatic reducing sugar tester uses DNS (3,5-dinitrosalicylic acid) method to chemically react with reducing sugar in an alkaline environment through DNS to generate colored substances, and the product is measured by spectrophotometer to calculate the content of reducing sugar in the sample. This method has the advantages of simple operation, high accuracy and good stability, and is one of the most widely used methods for the determination of reducing sugars.
Second, the operation steps of the automatic reducing sugar tester.
1.Sample Handling: The sample to be tested is subjected to appropriate treatment, such as grinding, filtration, etc., to obtain a clear and transparent solution.
2.Reagent preparation: Prepare the required reagents according to the requirements of the instructions, including DNS, sodium hydroxide, copper sulfate, etc.
3.Steps: Put the sample to be tested into the sample cup, add an appropriate amount of reagent, and shake gently to mix the solution thoroughly. Then put the sample cup into the automatic reducing sugar tester and operate it according to the instrument manual.
4.Data output: Wait for the output of the measurement results, and calculate the amount of reducing sugar in the sample according to the results.
3. Advantages of automatic reducing sugar tester.
1.High degree of automation: The automatic reducing sugar tester adopts automatic design, which can greatly reduce manual operation and improve detection efficiency.
2.High accuracy: The DNS method is used for the determination of reducing sugars, which has high accuracy and can meet the needs of various applications.
3.Good stability: The automatic reduced sugar analyzer adopts a precise mechanical system and control system to ensure the stability and reproducibility of the determination.
4.Easy to operate: The automatic reducing sugar analyzer has a friendly operation interface and simple operation steps, which is convenient for users to use.
5.Versatility: The automatic reducing sugar analyzer can be used not only for the determination of reducing sugar, but also for the measurement of other biochemical indicators, with a wide range of applications.
In a word, the automatic reducing sugar analyzer is an efficient and accurate biochemical analysis instrument, which is widely used in food, beverage, biological products and other fields. By understanding the knowledge of its detection principles, operating procedures, advantages and precautions, etc., the instrument can be better used and maintained, providing strong support for the development of related fields.
