Abstract

The invention discloses a method for analyzing cryopreserved whole blood by using constant-low-temperature supercontinuum integrated spectroscopy. The method is implemented on an analyzing instrumentfor cryopreserved whole blood. The method comprises the following four steps: realization of constant low temperature of an integrating sphere; initial calibration; constant-low-temperature supercontinuum integrated spectrum acquisition; and test result analysis. The method can be used in customs for detection, identification, database building, tracing and protection of cryopreserved whole blood.The invention has the beneficial effects that constant low temperature control of an inner cavity is realized by controlling flow via an electrically-operated valve and controlling liquid velocity via a liquid nitrogen pump, so the uniformity of a testing environment is guaranteed; thus, the repeatability and consistency of supercontinuum transmittance spectra testing of cryopreserved whole bloodsamples are improved, and deviation caused by heating of samples in conventional processes can be eliminated, so the recognition rate of whole blood of different species can be effectively improved.

Description

technical field [0001] The invention relates to a laser spectrum analysis method, in particular to a whole blood analysis method using a constant low temperature laser supercontinuous comprehensive spectrum technology, which is suitable for testing, building and screening of frozen whole blood samples of humans and animals, and belongs to photoelectric imaging. field. Background technique [0002] In the field of import and export, most countries take 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 species, their import and export control is 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 caused by blood exposure and harm to test personnel. Most of the existing blood te...
