Microwave Digestion Systems for Sample Preparation

Advantages of Microwave Chemistry

Microwave radiation is an extremely effective heating source in chemical reactions. Microwaves can accelerate reaction rates, increase yields, and achieve uniform and selective heating, thereby improving the reproducibility of the reactions and facilitating the development of cleaner and more environmentally friendly synthesis pathways. Compared with traditional heating methods, microwave heating can increase the rate of certain chemical reactions by 10 to 1000 times. In addition, using microwave radiation for heating is a very efficient process with extremely low energy consumption. This is because microwaves only heat the sample but not the instrument, thus resulting in significant energy savings. Since microwave digestion instruments can raise the temperature to above 800˚C in a short time, they eliminate the lengthy heating-up periods required by traditional resistance furnaces. This significantly reduces the associated energy costs.

Digestion Systems for the Preparation of Challenging Samples

Ultra Microwave Digestion System

Amerigo Scientific offers U2 pre-pressurized ultra microwave reaction system that is an integrated high-power, high-pressure microwave reactor designed for fast, efficient, and complete chemical transformations. It extends the capabilities of traditional digestion instruments, capable of handling refractory samples, accelerating complex reactions, and achieving precise control over experimental conditions.

Compared with traditional microwave systems, ultra microwave systems consume less acid, and feature a higher degree of automation and a lower operating cost. The U2 ultra microwave system is especially suitable for extremely difficult-to-digest samples, such as refractory polymers, graphite, carbon fibers, silicon carbide, some oxidized alumina, high-purity iridium, high-purity rhodium, radioactive samples, etc.
