原子荧光光度计无荧光信号输出,在检查试剂及进样流路、气路系统正常的情况下,应重点检查光电倍增管和相关的附属电路。本文介绍由于光电倍增管打拿极电阻断路导致的此类故障及排除。
Atomic fluorescence spectrophotometer no fluorescence signal output, in the check reagent and injection flow path, gas system is normal, the focus should be to check the photomultiplier tube and related ancillary circuits. This article describes such problems and their elimination as a result of the photodiode dynode resistance breaking.
