Patent ID: 7270783

Claim:
An analysis system comprising: a sample rack in which plural samples dissolved in protonated solvent are accommodated; a turntable for carrying sample containers and incrementally rotating to present the sample containers at various stations; a sample container supply means for supplying sample containers; a sample aspirating-and-dispensing means for aspirating each sample from said sample rack and dispensing said sample into said sample container; a solvent-removing means for evaporating off the protonated solvent from each sample and drying and solidifying the sample comprising nozzles for removal of the solvent by injecting gas into the sample container, the depth of the insertion of the nozzles into the sample container being increased as the progress of removal; a source of deuterated solvent; a solvent-dispensing means for dispensing a deuterated solvent from said source into each dried and solidified sample; a sample-stirring means for stirring the sample in which said deuterated solvent has been dispensed; a sample aspirating-and-transferring means for aspirating each sample dissolved in said deuterated solvent and transferring sample into a measuring portion; a sample recovery means for recovering the sample into a sample container from said measuring portion after measurement; a sample container recovery means for recovering the sample container in which the investigated sample has been recovered; and a control means for sequentially controlling the operation of the analysis system throughout sample processing.
