  • Patent number: 8364415
    Abstract: The present invention provides a melting curve analyzing method that can automatically analyze whether or not a peak is present in at least one of two temperature ranges. A signal differential value (A) having a maximum absolute value is searched for among signal differential values at respective temperatures. When a temperature (t1) indicating (A) is included in a temperature range (T1) that is either one of a predetermined temperature range TH and a predetermined temperature range TL, it is determined that (A) is a first peak. Further, a signal differential value (C) that is a first signal differential value after the absolute value changed from decreasing to increasing and a signal differential value (D) having an absolute value that is greatest next to the absolute value of (A) are searched for.

  • Publication number: 20130010293
    Abstract: A light emitter emits light with a plurality of wavelengths towards a test object held in a spectrophotometer tool. A light receiver receives the light passing through the test object. A detector detects absorbances of wavelength components from the light received by the receiver. An optical path length calculator compares, in the absorbances of the wavelength components detected, a wavelength component absorbance of light absorbed by a pigment that absorbs light with a wavelength other than a wavelength of light absorbed by an analyte in the test object and a predetermined value of the wavelength component absorbance to calculate an optical path length passing through the test object. A corrector corrects the wavelength component absorbance detected excluding the wavelength of the light absorbed by the pigment using the optical path length calculated by the optical path length calculator to calculate a corrected wavelength component absorbance in a reference optical length.
