A solvent extraction composition is comprised of one or more orthohydroxyarylaldoximes and one or more othohydroxyarylketoximes, and one or more equilibrium modifiers in an amount providing a degree of modification of the orthohydroxyarylaldoximes from about 0. A first detector detects operation of the manipulator and outputs a signal representing the detection result. The representation includes data defining an experiment object having a plurality of properties derived from the chemical experiment. The learning unit 3 learns a quality dictionary based on the calculated matching score and the degradation pattern. The information relating to the projectile is modulated to the carrier frequency in the modulator. The base support element is exposed when the first extension part is removed.
