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.

Product Description : Round-bottom flasks (also called round-bottomed flasks, Flasks, round bottom, or R B Flasks) are types of flasks having spherical bottoms used as laboratory glassware, mostly for chemical or biochemical work.They are typically made of glass for chemical inertness; and in modern days, they are usually made of heat-resistant borosilicate glass. There is at least one tubular section known as the neck with an opening at the tip. Two or three-necked flasks are common as well. Round bottom flasks come in many sizes, from 5 mL to 20 L, with the sizes usually inscribed on the glass. In pilot plants even larger flasks are encountered.
