Method and device for automatically detecting substances for analyses

A method for automatically detecting biological substances for analyses of samples (11) applied to plates (10),

• wherein
• a) in a magazine (14), in which a large number of plates (10) are stored,
• b) a gripper (15) takes hold of a plate (10) in the magazine (14) in each case and delivers it to a measuring head (100) for identification,
• c) the measuring head (100) identifies the position and the shape of the samples (11) by means of sensors,
• d) a microprocessor (101) analyzes their position and shape,
• e) the relative orientation of an extraction head (1) and of a counterpart extraction head (2) with respect to the plate (10) is adjusted by the microprocessor (101),
• f) the extraction head (1) and the counterpart extraction head (2) extract the desired substances, and as little as possible of interfering matrix, from the sample (11),
• g) the extraction head (1) and the counterpart extraction head (2) are cleaned of residues,
• h) the measuring head (100) is brought together with the next sample (11),
• i) the sequence of the process from c) to h) is repeated with the new sample until all the desired samples (11) on a plate (10) are processed,
• j) the gripper (15) returns the plate (10) into the magazine (14),
• k) the procedure according to b) to j) is repeated until all the desired plates (10) of a magazine (14) are tested,
• l) after each extraction process according to f, the desired substances and matrix are forwarded for further processing.
