Abstract

The invention discloses a high-throughput refractive index measuring chip, a measuring device and a measuring method and belongs to the field of precision instruments. The measuring chip comprises a chip main body. One surface of the chip main body is an optical plane. The optical plane contacts with an outer refractive index measuring device in a surface contact way. The chip main body is provided with at least two grooves for containing a liquid to be detected. The depth of the grooves is smaller than or equal to thickness of the chip main body. Two ends of the groove are respectively provided with a liquid input channel and a liquid output channel. The invention also provides the high-throughput refractive index measuring device. The measuring device comprises the measuring chip. The invention also provides the high-throughput refractive index measuring method. The method realizes simultaneous measurement of the refractive indexes of a plurality of liquids. The device has high measurement efficiency and good consistency of measurement results and difficultly introduces a random error.

Description

technical field [0001] The invention belongs to the field of high-throughput refractive index measurement, and more specifically relates to a high-throughput refractive index measurement chip, device and method. Background technique [0002] A refractometer is a device that measures the refractive index of a material. The traditional Abbe refractometer and most of the current improved digital refractometers can only measure one liquid at a time. If it is necessary to accurately measure the refractive index of multiple substances, it is generally achieved through multiple measurements. The method of multiple measurements has the defect of low measurement efficiency, and may also introduce random measurement errors. [0003] High-throughput measurement is a trend in the development of automated instruments. At present, there is no multi-channel refractive index measurement device, therefore, it is necessary to develop a high-throughput or large-throughput refractive index m...
