<p><P>PROBLEM TO BE SOLVED: To provide a liquid-liquid extraction method for sample with which liquid-liquid extraction prompt and improved in reproducibility is implemented and which is compact and suitable for on-site measurement or the like, and a liquid-liquid extraction apparatus for sample. <P>SOLUTION: According to a liquid-liquid extraction method for sample, a liquid sample is discharged while being made into minute droplets by a minute droplet discharge device, and dripped into an extraction solvent which does not have compatibility with the liquid sample and through an interface with the extraction solvent formed from the sample made into minute droplets, contents contained in the liquid sample are shifted into the extraction solvent. Furthermore, a liquid-liquid extraction apparatus for sample comprises a sample feeding tube which supplies the liquid sample, the minute droplet discharge device with which the liquid sample is discharged while being made into minute droplets, and a solvent holding container which holds the predetermined amount of the extraction solvent that does not have compatibility with the liquid sample. The sample made into minute droplets by the minute droplet discharge device are dripped into the extraction solvent held by the solvent holding container, and moved in the solvent for a predetermined time. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
