Microfluid analytical systems (part 1)

The paper presents an analytical review of the literature on microfluid systems (MFAS). The main advantages of MFAS, which define the high analytical potential of the instrument, are indicated. The physical operating principles of MFAS are discussed. The relationships for calculation of MFAS characteristics, such as efficiency, geometrical dispersion, electrophoresis quality, are given. The paper also provides an outline of the processes of microfluidics, including the pumpless one, of various microfluid chip designs and process technologies, of miniature complete analysis systems. Main trends in MFAS development are discussed, and the systems, which are now key to progress in analytical instrumentation in Russia, are highlighted.
