Milk small-molecule bioactive peptide detection device

Abstract

The invention relates to the technical field of protein detection, in particular to a milk small-molecule bioactive peptide detection device. The device comprises a shell and a fast atom bombardment ionization protein mass spectrometer, a vertical partition plate is arranged in the shell, the interior of the shell is divided into an equipment bin and an operation bin through the partition plate, afast atom bombardment ionization protein mass spectrometer for detecting a small molecular bioactive peptide is mounted in the equipment bin, a storage plate is transversely arranged in the operationbin, an equipment storage box internally provided with experimental equipment extends out to facilitate taking and using of the experimental equipment, and the extending equipment storage box can remind experimenters to put the experimental equipment back into the equipment storage box in time. The steps of an experimenter are recorded through a camera, it is judged whether the experimental operation of the experimenter is standard or not conveniently by reading the content in the memory, and when someone questions the conclusion of an experiment, a video record can be called for responsibility investigation.

Description

technical field [0001] The invention relates to the technical field of protein detection, in particular to a detection device for small-molecule bioactive peptides of milk. Background technique [0002] Milk small molecular bioactive peptides are an important indicator for testing the nutritional components in milk. Generally, it is detected by automatic Edman degradation method or DNA translation method, but these two methods are often not accurate enough in the detection of small molecular bioactive peptides. With the development of mass spectrometers, the detection of small molecular bioactive peptides basically tends to be detected by mass spectrometers. [0003] Fast atom bombardment mass spectrometry is a soft ionization technique for mass spectrometers. Hydrogen ions are generated by the discharge of the hydrogen ion gun. The high-energy hydrogen ions pass through the hydrogen-filled charge exchange chamber of about I3.3322Pa (10 Torr), and after the resonant charge ...

Problems solved by technology

[0004] At present, the fast atom bombardment mass spectrometer is a separate instrument. When in use, the experimental instruments that need to be used are not easy to place, and the experimental operations of the experimenters cannot be traced. It is inconvenient to use and needs to be improved.
