The new Trinder's reagent is a highly water-soluble aniline derivative that has been widely used in diagnostic tests and biochemical tests. In the colorimetric determination of hydrogen peroxide activity, it has many advantages compared with conventional color reagents. The new Trinder's reagents are stable enough to be used in solutions and test line inspection systems. Currently chromogen substrates (new Trinder's reagents) include TOOS, TOPS, ADOS, ADPS, ALPS, DAOS, HDAOS, MADB, MAOS, etc. These new chromogens actually have similar reaction principles to traditional chromogens, but they have more advantages. We mainly understand the MAOS among them. The full name of MAOS is N-ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethylaniline sodium salt. It is a highly water-soluble aniline derivative of the new Trinder's reagent. Which has a pivotal position. It is a water-soluble reagent that can be applied to the enzymatic photometric determination of hydrogen peroxide, and is widely used in diagnostic testing and biochemical tests. Reasons for the discoloration of the reagent solution: Color-developing substrates such as MAOS are all new Trinder's reagents, which are derivatives of highly water-soluble aniline sodium salt, which will produce red or yellow substances after being oxidized. Trinder's reagent powder is not easy to be oxidized. It needs to be sealed and refrigerated after preparation. If the solution is exposed to the air for a long time and the temperature is high, they may be slowly oxidized by the oxygen in the air. Discoloration of the solution occurred. MAOS is sensitive to light and sensitive to humidity. Therefore, when we store, the storage temperature of cold storage is between 0-10, and the temperature of frozen storage is below 0. If the storage temperature is not specified, in principle, it should be stored in a cool place below 15C. Hubei Xindesheng has focused on the research and development of a batch of new Trinder's reagents and other color reagents. The new reagent has more advantages: such as high water solubility, UV absorption of the color reaction product> 540nm; color reaction requires a wide pH range, and the activity of a variety of enzymes can be guaranteed during the reaction; color reaction sensitivity is higher and can be used For the determination of very small amounts of analytes. And it has considerable product advantages, purity: >99%, good water solubility, stable process, and can ensure the appearance of the product is pure white crystal powder. Welcome everyone to inquire.
Luminol has become one of the most widely used chemiluminescent reagents due to its advantages of high quantum yield, easy synthesis, and good water solubility. Its development process is the same as the arduous process of human beings. From the beginning, there is not much understanding, to the current glow and fever, it can only be summarized in one sentence: gold always shines. In the future, there may be more uses we don't know to benefit our lives. We only need to learn more about it to discover its unlimited potential as soon as possible. Application in the analysis of inorganic substances Using inorganic ions to enhance or inhibit the chemiluminescence of the luminol system, these metal ions can be measured. It is worth pointing out that some metal ions have higher catalytic activity than metal ions after being combined with complexing agents. For example, using the luminol-H2O2-silver phenanthroline system, the detection limit of silver ions can reach 2.7 10-g/L3. The use of sensitizers can improve the sensitivity of detection. The sensitization effect of triphenylmethane derivatives on the luminol luminescence system. It was found that Coomassie Brilliant Blue G250 had the best sensitization effect on the luminol-H2O2-Cu2+ system. A reverse flow injection technique was used to establish a measurement of Cu2+. The new method has a detection limit of 15. The use of the local concentration effect of surfactants to achieve micelle sensitization has been increasingly used in luminescence analysis. For example, the reversed micellar system FIA method is used to measure V4+, the detection limit is Luminol chemiluminescence analysis has been widely used in various fields, and new methods and new technologies are constantly emerging, especially the combination with FIA, HPLC and other technologies, which overcomes the shortcomings of poor selectivity in luminescence analysis and makes the analysis more flexible. Emblem and accuracy. Because of Rumi's stable performance and low price, practical application research and analysis will have broader application prospects.
