ABSTRACT:
Proposed is dispensing technology capable of reliably spotting a biological sample on a solid phase. A head chip applies a voltage pulse between a diaphragm and separate electrodes based on a drive control signal output from a head driver IC, and discharges a solution containing protein filled in a pressurized chamber as a result of the elastic deformation of the diaphragm. A drive pulse generation circuit generates a drive voltage pulse and supplies this to the head chip in order to discharge a solution containing protein from the head chip. The drive current detection circuit detects a drive current flowing between the diaphragm and separate electrodes. Since the waveform of the detected drive current and the peak current value and so on differ in the case where the discharge status is normal and in the case where it is abnormal, a defective discharge can be discriminated by detecting such change.
