Abstract

The invention discloses an experimental sample preparation device, which comprises: a pre-processing storage unit for storing the pre-processing experimental sample disk; a grinding unit for grinding the experimental sample and communicating with the pre-processing storage unit, It includes an auxiliary material filling part, a grinding part and a certain volume part connected in sequence; several transmission channels run through the pre-processing storage unit and the grinding unit for transporting the experimental sample disk. The adoption of the technical scheme can solve the problems of heavy workload and heavy tasks during manual operation in the determination of the chlorophyll content.

Description

technical field [0001] The invention belongs to the technical field of test sample preparation, in particular to an experimental sample preparation device. Background technique [0002] Chlorophyll content is an important observation index in the research of fresh-keeping and processing of agricultural products and in the process of cultivating new varieties of crops. Chlorophyll is the main pigment for photosynthesis in plants. It is a family of lipid-containing pigments located in thylakoid membranes. Chlorophyll absorbs most of red and violet light but reflects green light, so chlorophyll appears green, and it plays a central role in light absorption for photosynthesis. Chlorophyll is a magnesium porphyrin compound, including chlorophyll a, b, c, d, f, prochlorophyll and bacteriochlorophyll. Chlorophyll is not very stable, light, acid, alkali, oxygen, oxidant, etc. will cause it to decompose. Under acidic conditions, chlorophyll molecules can easily lose the magnesium ...
