Filed: 1990-03-14
Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for quantitative analysis of a material sample, such as whole grain, as a function of optical characteristics thereof includes a light source and a solid state detector of silicon or other suitable construction.  A material sample is positioned between the light source and the detector, and light energy is focused through the sample onto the detector at a plurality of preselected wavelengths in the ???r-infrared range of 800-1100 nm.  Illumination wavelength is selectively controlled by an opaque disc having a central axis and a plurality of apertures around the periphery at uniform radius from the disc axis.  A plurality of filter elements are carried by the disc over respective ones of the peripheral apertures and have transmission characteristics corresponding to the plurality of preselected wavelengths.  The filter elements are carried in a continuous circumferential array around the disc periphery, with the array including at least one opaque section for chopping light energy incident on the detector. The disc is rotated about its axis in a continuous motion so that each filter element in turn intersects light energy transmitted through the sample.  Analysis electronics is responsive to  light energy incident on the detector at the plurality of preselected wavelengths to indicate a preselected characteristic of the material sample. [PLA-4/RCC]

Abstract: ABSTRACT OF THE DISCLOSURE The invention provides an improved procedure for the precise quantitation of organic oxidants in a solution with hydrogen peroxide in which the peroxide is removed by the addition of catalase to scavenge the same.  Surprisingly, the catalase does not affect the organic oxidant, and the procedure can accurately quantitate even minute amounts of the organic oxidant.  The inventive method is especially effective in quantitating peracid generated enzymatically although it can be used for chemically generated organic oxidants.
