Problems solved by technology

The movement of the sample cell is mainly realized by the stepping motor and the corresponding transmission mechanism. Since the sample often contains strong acid and strong alkali reagents, the stepping motor and its transmission mechanism are easy to be corroded and oxidized. In addition, because the sample cell The pipeline is usually connected. During the movement of the sample cell, the pipeline needs to be bent frequently, which is prone to fatigue damage. In addition, multiple pipelines will also increase the load of the sample cell during movement, resulting in poor position repeatability.

Abstract

The invention especially relates to a spectrophotometer and specifically discloses a static multi-sample-cell spectrophotometer, belonging to the technical field of measurement of spectral information. According to a technical scheme in the invention, two or more sample cells of the static multi-sample-cell spectrophotometer are fixedly arranged; a light beam irradiates a first mobile reflector; and the first mobile reflector moves to a position relative to a to-be-detected sample cell under the driving of a drive unit to allow the light beam to be reflected, to pass through the to-be-detectedsample cell and then to enter a receiving device. The static multi-sample-cell spectrophotometer realizes sample analysis by moving the light beam and the sample cells are stationary, so the static multi-sample-cell spectrophotometer perfectly overcomes the problems of pipeline fatigue of the sample cells, poor positioning repeatability, and proneness of a transmission mechanism to corrosion in the prior art.

Description

technical field [0001] The invention belongs to the technical field of spectral information measurement, in particular to a spectrophotometer. Background technique [0002] A spectrophotometer, also known as a spectrometer, is mainly composed of a light source, a monochromator, a sample chamber, a detector, a signal processor, and a display and storage system. It is mainly used in the fields of drug analysis, food analysis, and pollutant detection. [0003] The light source in the spectrophotometer is used to generate beams of multiple wavelengths. The beams of multiple wavelengths pass through the monochromator and retain the beams of specific wavelengths. The sample to be analyzed is located in the sample cell. After the beams of specific wavelengths pass through the sample, some The light is absorbed, and the degree of absorption of the beam is recorded, which gives the amount of substance in the sample. In practical applications, in order to improve work efficiency, tra...
