Изобретение предназначено дл исследовани мутных растворов методом светорассе ни .The invention is intended to investigate turbid solutions by light scattering.
Известны фотоэлектрические нефелометры, содержащие источник излучени , двухлучевую оптическую систему формировани светового потока, рабочую и эталонную кюветы, фотоприемники и систему регистрации.Photoelectric nephelometers are known that contain a radiation source, a two-beam optical system for forming a light flux, a working and reference cell, photodetectors, and a recording system.
Дл повышени точности измерений степени мутности в предлагаемый нефелометр введены два светонепроницаемых цилиндра, охватывающие кюветы, снабженные средством дл перемещени , а эталонна кювета по внутренней поверхности покрыта равномерным слоем отражающего покрыти , например белым целлулоидом .To improve the accuracy of turbidity measurements, two opaque cylinders were inserted in the proposed nephelometer, covering cuvettes equipped with means for moving, and the reference cuvette on the inner surface is covered with a uniform layer of a reflective coating, such as white celluloid.
На чертеже изображена оптическа схема предлагаемого нефелометра. Луч света от источника 1 делитс на два пучка - измерительный и эталонный. Измерительный луч через отверстие в стойке 2 и линзу 3 понадает на кювету 4, где рассеива сь, через вертикальный стекл нный стержень 5, наход щийс в центре светонепроницаемого цилиндра 6, попадает на фотоприемник 7.The drawing shows the optical layout of the proposed nephelometer. The light beam from source 1 is divided into two beams - measuring and reference. The measuring beam through the hole in the rack 2 and the lens 3 pona at the cuvette 4, where it is scattered, through a vertical glass rod 5 located in the center of the light-tight cylinder 6, falls on the photodetector 7.
Эталонный луч через отверстие в стойке 8 V линзу 9 попадает па кювету 10, котора поThe reference beam through the hole in the rack 8 V lens 9 enters the cuvette 10, which
внутренней поверхности покрыта белым целлулоидом . Рассе нный световой поток через вертикальный стекл нный стержень 11, наход щийс в центре светонепроницаемого цилипдра 12, нопадает на фотоприемник 13. Дл изол ции рассе нного света введены металлические пластины 14 и 15. Дл перемещени кювет установлены подставки 16 и 17, зубчатые колеса 18 и 19. Перемещение кювет фиксируетс системо регистрации.The inner surface is covered with white celluloid. The diffused light flux through the vertical glass rod 11, located in the center of the light-tight cylinder 12, falls on the photodetector 13. Metal plates 14 and 15 are inserted to isolate the scattered light. Stands 16 and 17, gears 18 and 19. The movement of the cuvette is recorded by the recording system.
