Rapid automated analyses performed in parallel.

The analytical concept of monitoring chemical reactions simultaneously in a number of discrete samples is explored. A new class of analyzers based on this concept has been introduced. One such system uses centrifugal force to transfer and mix reagent and sample in a multiple-cuvet rotor. A second, completely new system (CHAMP) is introduced here. In both systems, data signals can be generated at 3.3-ms intervals. Thus, these devices are potentially very fast and can be interfaced directly with a computer, which facilitates their integration into computerized information systems of hospitals.
