The central controlling unit 20 includes a measurement data calculating means (210) for generating measurement data by making calculation on the crude data sent from each terminal unit (30).
摘要:
A total reflection cell has a total reflection prism on at least one surface thereof. A mixed solution containing a gold colloid labelled antibody which is adsorbed on a gold colloid is stored in the total reflection cell, and a sample solution containing an antigen causing antigen-antibody reaction with the antibody is added thereto for forming a gold colloid labelled immune complex. A measuring beam is introduced into the total reflection prism from an incident optical system at an angle θ of incidence causing total reflection and an outgoing beam from the total reflection prism is received by a measuring optical system, thereby measuring absorption by the gold colloid labelled immune complex and carrying out qualification and determination of the antigen.

As to reaction solutions in which the amount of each potassium ferricyanate, glucose oxidase and glucose substrate are set at a constant value while glucose concentrations are varied, intensity changes of peaks at a shift wavenumber of 2081 cm.sup.-1 in light scattering spectra are measured every 10 seconds, the maximum values of the intensity changes of the peaks at the respective glucose concentrations obtained, for obtaining a calibration curve from correlations between the maximum values of the reaction velocities and the glucose concentrations. The calibration curve is employed for carrying out quantitative measurement of an unknown sample.

An excitation beam from a laser is passed through a bandpass filter, and applied to a sample by a collimator lens. An optical adjusting part comprising a camera lens and a converging lens is provided for receiving scattered light from the sample, so that the camera lens receives the scattered light and converts the same to a parallel beam. The converging lens has chromatic aberration, and receives and converges the parallel beam from the camera lens. An inlet slit of a spectroscope is provided as an inlet port on a converging position by the converging lens. This inlet slit is a circular hole having a diameter of about 200 .mu.m. The inlet slit is arranged on a position for converging anti-Stokes-Raman scattered light through the chromatic aberration of the converging lens.

A sample solution is stored in a total reflection cell, and a measuring beam is introduced from an incident optical system to be totally reflected, for measuring a total reflection absorption spectrum. Hydrogen peroxide contained in the sample solution is determined on the basis of absorbance at the position of any absorption peak of the spectrum which is present at 1200 to 1500 cm.sup.-1 or 2600 to 3000 cm.sup.-1. Hydrogen peroxide contained in an aqueous solution can be simply quantitatively analyzed through optical analysis.

A Raman scattered light measuring apparatus comprises a near infrared semiconductor laser diode as a light source for irradiating a sample with excitation light, while a photoreceiving part for receiving Raman scattered light from the sample comprises a bandpass filter having a vibration wavenumber which is specific to a sample component to be measured as a central wavelength of its transmission region, and a detector consisting of a photodiode of Ge, InAs or InGaAs or a photomultiplier having sensitivity in a near infrared region for detecting Raman scattered light which is transmitted through the bandpass filter.
摘要:
An excitation beam generated from a light source is separated into a measuring beam and a reference beam by an optical path adjusting optical system including a beam splitter, so that the measuring beam is applied to a sample in a cell. Raman scattering light which is generated from the sample is detected by a spectral detector including a spectroscope through a scattering light path adjusting optical system and a wavelength selector. In a spectrum obtained by the spectral detector, a peak of Raman scattering in which wavenumber shift from the wavelength of the excitation beam is present at 800 to 920 cm.sup.-1 is employed to make quantitative measurement of hydrogen peroxide. Hydrogen peroxide contained in an aqueous solution can be simply quantitatively analyzed through optical analysis means.

In order to quantitatively measure an Amadori compound by a simple optical method utilizing light scattering, a sample containing an Amadori compound which is stored in a cell is irradiated with excitation light from an He--Ne laser unit so that scattered light from the sample is received and separated into its spectral components for obtaining a light scattering spectrum, and a light scattering peak existing at 820 to 840 cm.sup.-1, 1655 to 1660 cm.sup.-1, 2000 to 2020 cm.sup.-1, 2080 to 2100 cm.sup.-1, 2460 to 2470 cm.sup.-1 or 2530 to 2600 cm.sup.-1 in shift wavenumber with respect to the excitation wavelength in the light scattering spectrum is detected by a detector. The saccharide concentration or the saccharification ratio of the Amadori compound is measured by a calibration curve through the peak intensity or the peak integral value of the light scattering peak.
