The present invention addresses the problem of providing a method for identifying an optical isomer of a low-molecular-weight compound, the method making it possible to analyze whether the optical isomer is in a D-form or an L-form for each measured low-molecular-weight compound. This method for identification comprises: a low-molecular-weight compound electrophoresis step which is performed using a device including measurement electrodes for measuring a tunnel current at the time when a low-molecular-weight compound passes therethrough, and in which a voltage is applied so as to straddle the measurement electrodes of the device, thereby allowing the low-molecular-weight compound contained in a sample solution to pass through the measurement electrodes by electrophoresis; a measurement step in which a tunnel current at the time when the low-molecular-weight compound passes through a gap between the measurement electrodes is measured; and an analysis step in which it is determined, from the measured tunnel current, whether an optical isomer is in a D-form or an L-form for every measured low-molecular-weight compound.
An identifying method of optical isomers of a low-molecular compound, wherein the identifying method is performed by using a device comprising measuring electrodes for measuring tunnel current occurring when the low-molecular compound passes between the measuring electrodes, the identifying method comprising:
