Abstract: A switch apparatus, includes: a base module including a base case, and a moving magnet movably mounted in the base case; and a manipulation module including a manipulation case, and a first magnet fixedly mounted in the manipulation case, wherein the moving magnet moves between a hold position and a releasable position, the hold position refers to a position in which the manipulation module is held onto the base module as an attractive force acts between the moving magnet and the first magnet, and the releasable position refers to a position in which the manipulation module is releasable from the base module as a repulsive force acts between the moving magnet and the first magnet.

Abstract: The present application discloses a method of identifying an active agent in a sample, which steps include subjecting the sample to a plurality of separation principles in parallel, obtaining an active fraction from each separation principle, and profiling physiochemical properties of the active fraction so as to obtain the agent that is common in each of the fractions, thereby identifying the agent of interest.
