Abstract
An object of the present invention is to provide an optical measurement apparatus equipped with an ion-exchange resin for pretreating a sample, thereby enabling the concentration of component in the sample to be measured with higher accuracy. The optical measurement apparatus of the present invention includes, in addition to the ion-exchange resin, an optical measurement section for measuring, based on the optical characteristics of the component, the concentration of the component in the sample after the sample is passed through the ion-exchange resin.
Claims16
An optical measurement apparatus comprising:
- an ion-exchange resin;
- a synthetic absorbent;
- an optical measurement section for measuring the concentration of an optically active substance in a sample based on optical characteristics of said optically active substance after said sample is passed through said ion-exchange resin and said synthetic absorbent;
- a control section for continuously monitoring a measurement result from said optical measurement section;
- and
- a regenerating section for regenerating said ion-exchange resin with a regenerant, wherein
- said control section makes a determination, based on the monitoring of said measurement result, as to whether ion-exchange ability of said ion-exchange resin has become saturated or not, and
- said control section conducts a regeneration by said regenerating section when said control section determines that said ion-exchange resin has become saturated.
