[0002] The matrix was once called "an environment for an analyte", which refers to everything in the sample except the analyte. The matrix is ​​an amorphous colloid composed of biological macromolecules, colorless and transparent, with a certain viscosity, and tissue fluid in the pores. The physical properties of the extracellular matrix are mainly affected by the polysaccharide groups carried by proteoglycans in the extracellular matrix. Proteoglycans are polysaccharide and protein complexes formed by glycosaminoglycans covalently linked to linear polypeptides. Another matrix is ​​an artificial soil used for plant cultivation.

[0003] In the prior art, when weighing a matrix, a matrix scale is usually used, on which a screen is installed. The matrix is ​​sieved through the screen and then falls into a weighing bucket for weighing. However, since the screen sieves the matrix slowly, the weighing efficiency is low.
