Abstract:

During last two decades, flow chemistry has been a very intensively developing field of modern methods of chemical synthesis on a laboratory scale. What is particularly interesting, the development on numerous techniques and methods in flow chemistry, has practically never been referred to the laboratory flow analysis methods developed since the 1950s. The efficient and reproducible treatment of samples or chemical transformation of analytes is among commonly recognized attributes of flow analysis. At the same time, this is the fundamental element of synthetic methods in flow chemistry. On the other hand, the monitoring of progress and yield of syntheses under continuous flow conditions, carried out in a discrete mode after a given process in collected fractions, has been increasingly replaced by continuous monitoring with on-line instruments incorporated into flow setups. This is exactly what is considered as a typical application of flow analysis. Other methods in flow analysis, as well as laboratory flow synthesis are being developed in numerous leading research centers on a world scale; hence it is bewildering to find that practical research activity in each of these fields does not involve referring one to another. The flow mode of conducting chemical syntheses facilitates chemical processes through the use of on-line analytical monitoring of occurring reactions, the application of solid-supported reagents to minimize downstream processing and computerized control systems to perform multi-step sequences. They are exactly the same attributes as those of flow analysis, which has solid place in modern analytical chemistry in several last decades.
