    Abstract: Apparatus and method are disclosed in which a beam of radiant energy (16) is passed into a medium at a wavelength selected to cause a response of an analyte in the medium or of a sensor (10, 14) exposed to the medium, the sensor comprising a reagent whose optical properties change in response to the presence of the analyte in the medium. A perturbing pulse of energy (22) is passed into the medium to alter the response of the analyte or reagent to the beam of radiation; and the time rates of change in the intensity of the transmitted radiant energy are measured (18, 24, 26, 28) while the response is changing due to the influence of the perturbing pulse, after the perturbing pulse starts or ends or both, such rates of change being proportional to the concentration of the analyte in the medium. Both the beam of radiant energy and the perturbing pulse may be passed through optic fibers into the medium or sensor.

    Abstract: A scatter signal is produced from light scattered by a precipitate formed by a chemical reaction and non-specific scatter sources. A blanking signal is produced for a scatter signal from light scattered only by the non-specific scatter sources that contribute to the scatter signal, and the blanking signal is subtracted from the scatter signal to dynamically produce a signal indicative of the difference between the scatter signals to reduce the effects of non-specific scattering sources in determining the rate of change of the light scattered by the precipitate. One of the scatter signals may be stored and then combined with the other, or the signals may be measured simultaneously and then combined.

    Abstract: Errors in applying liquid sample are judged during biochemical analysis wherein a droplet of liquid sample is applied to an analysis medium containing a reagent, which chemically reacts with a specific constitutent in the liquid sample, the analysis medium is then incubated, the optical densities of the analysis medium are determined, and concentration of the specific constituent in the liquid sample is determined from the optical densities of the analysis medium thus determined. The method for judging errors in applying a liquid sample comprises the steps of determining the optical density of the analysis medium plural times with the passage of time while the analysis medium is being incubated, and calculating the difference between the maximum value and the minimum value of the optical densities thus determined for the analysis medium. The difference is compared with a predetermined threshold value. In cases the difference is smaller than the threshold value, it is judged that errors occurred in applying a liquid sample to the analysis medium.
