Patent ID: 7746468

Claim:
An analysis system comprising: an automatic sample feeding apparatus for selecting a designated sample from a plurality of prepared samples and reserving said selected sample as a target sample, or changing a target sample; an optical measuring apparatus including light source means for emitting light to a sample provided by said automatic sample feeding apparatus or a sample containing components of said provided sample, and light detection means for detecting light obtained through said sample in connection with said light emitted from said light source means; and a control apparatus for controlling said automatic sample feeding apparatus and said optical measuring apparatus, wherein: said optical measuring apparatus includes light blocking means adapted to be selectively interposed in a light path between said light source means and said light detection means to block off said light emitted from said light source means, and dark-current measuring means operable to measure a dark current in said light detection means under a condition that said light emitted from said light source means is blocked off by said light blocking means; and said control apparatus is operable to control said automatic sample feeding apparatus and said optical measuring apparatus in such a manner that said optical measuring apparatus performs said operation of measuring said dark current, during a time period where said automatic sample feeding apparatus performs said operation of selecting, reserving or changing a target sample.
