ABSTRACT

Photomultiplier tube (PMT) is a commonly used optical detection device in life science instruments, and its performance is crucial to the accuracy and sensitivity of the instrument. This article provides a detailed analysis of the accuracy of PMT bias circuits and proposes some improvement methods to enhance the performance of PMT. By introducing temperature compensation and stability improvement techniques, we have successfully suppressed the adverse effects of temperature and parameter drift on the PMT bias circuit, thereby improving the accuracy and stability of voltage division. The experimental results indicate that these improved methods have made significant progress in the application of photomultiplier tubes in life science instruments, providing effective solutions for precise measurement and reliability of the instruments. These improvement methods provide useful guidance and reference for further improving PMT performance and developing more advanced life science instruments.
