Isometric spiral multipoint ultraviolet spectrum cryopreserved serum analyzer

Abstract

The invention discloses an isometric spiral multipoint ultraviolet spectrum cryopreserved serum analyzer. The analyzer is composed of a machine body and internal components arranged in the machine body, wherein the internal components mainly include a Raspberry Pi, an ultraviolet raman laser, an ultraviolet raman probe, a spectrograph, a sample chamber, a direct-current stabilized power supply, atouch screen, a liquid nitrogen pump, a liquid nitrogen bottle, an electric controlling and moving assembly and an auxiliary component. The isometric spiral multipoint ultraviolet spectrum cryopreserved serum analyzer disclosed by the invention has the advantages that a mode that the flow is controlled by an electric valve and the liquid velocity is controlled by the liquid nitrogen pump is utilized, and low-temperature and constant-temperature control in an inner cavity is achieved; thus, test environment uniformity is ensured, and test repeatability is ensured; for a cryopreserved serum sample test, constant-low-temperature isometric spiral multipoint ultraviolet raman fluorescence spectra collection is performed, principal component analysis is performed on spectrum mean vectors and spectrum variance vectors, contingency and deviation of a single-point test are eliminated, and recognition rates of different species of serums can be effectively improved.

Description

technical field [0001] The invention relates to a laser spectrum analyzer, in particular to a serum analyzer using equidistant spiral multi-point ultraviolet spectrum technology, which is suitable for testing, building and screening frozen serum samples of humans and animals, and belongs to the field of photoelectric imaging. Background technique [0002] In the field of import and export, most countries adopt strict control measures on the import and export of blood products. Since the blood components of humans and animals contain important biological information such as the genetic characteristics of the species, their import and export controls are very strict, and special instruments and equipment are required for testing. [0003] Due to the particularity of blood products, the test equipment is required to be non-contact, so as to avoid denaturation and harm to test personnel caused by blood exposure. Most of the existing blood testing equipment is based on flow cyto...
