ALIQUOTING METHOD FOR AUTOMATIC SAMPLE EXAMINATION AND MEASUREMENT INSTRUMENT

摘要

In an automatic sample examination and measurement instrument for use in conducting random measurement concerning a plurality of items, the measurement accuracy and measurement reproducibility are improved, and failure, which is ascribed to inclusion of bubbles, of an aliquoting apparatus is prevented. Diluent is fed into sample-containing dilution vessels (11) by an aliquoting means so as to prepare diluted samples to be used for measurement. In order to remove small bubbles (13) produced during the preparation of such diluted samples, a predetermined quantity of diluted samples (12) are sucked from upper surfaces thereof by the aliquoting means, discharged into waste liquid cups, and discarded. The diluted samples (12) remaining in the dilution vessels (11) are used for measurement. Thus, the measurement accuracy and measurement reproducibility are improved, and failure, which is ascribed to inclusion of bubbles, of the aliquoting apparatus is prevented.
