Description

technical field [0001] The invention relates to a novel luminescence measuring instrument, which belongs to the technical field of medical equipment. Background technique [0002] Luminescence immunotechnology is a method that combines luminescence and immune responses to detect antigens or antibodies. Using micro-multiplication technology, it has good sensitivity and specificity; the detection range is very wide, from traditional proteins, hormones, enzymes to drugs can be detected. The photomultiplier tube used is a vacuum electronic device that converts weak optical signals into electrical signals, and can measure extremely weak radiation power with a wavelength of 200-1200 nanometers in low-level photometry and spectroscopy. [0003] For an automatic luminescence analyzer, it is often necessary to measure a number of samples continuously. The accuracy of the position of the luminescence microplate directly affects the accuracy of the measurement results. In the existing...

Problems solved by technology

[0003] For automatic luminescence measuring instruments, it is often necessary to continuously measure a certain number of samples. The position accuracy of the luminescent microplate directly affects the accuracy of the measurement results. The positioning between the microplate well and the reading head in the existing automatic luminescence measuring instrument is very difficult It is difficult to maintain the accuracy of long-term operation, and the adjustment of positioning is also very troublesome, so it is difficult to realize full automation of long-term operation
