PROCEDURE MEASURING CONCENTRATION OF SUGAR AND SACCHARIMETER FOR ITS REALIZATION Russian patent published in 2004 - IPC

FIELD: optical instrumentation engineering. SUBSTANCE: invention refers to polarimetric measurements of concentration of saccharose in solutions which can be utilized in medical, sugar and chemical industries. Intensity of linearly polarized light beam passed through light filter, first polarization filter, examined solution and second polarization filter is measured in first measurement channel. Second measurement channel is inserted in which light beam is directed through light filter, polarization filter and examined solution. Transmission factor of each channel relative to blank test carrying no examined substance is measured and concentration C of sugar is found by formula , where l is length of optical channel; [α] is specific rotation of polarization plane of sugar; T₁ is transmission factor of first channel; T₂- is transmission factor of second channel. EFFECT: diminished overall dimension of saccharimeter, simplified design of optical unit and complete elimination of kinematics in saccharimeter. 2 cl, 1 dwg
