ABSTRACT:
A portable fast analyzer is provided that uses a magnetic clutch/brake to rapidly accelerate the analyzer rotor, and employs a microprocessor for automatic analyzer operation. The rotor is held stationary while the drive motor is run up to speed. When it is desired to mix the sample(s) and reagent(s), the brake is deenergized and the clutch is energized wherein the rotor is very rapidly accelerated to the running speed. The parallel path rotor that is used allows the samples and reagents to be mixed the moment they are spun out into the rotor cuvetes and data acquisition begins immediately. The analyzer will thus have special utility for fast reactions.
