9317489 Walker A Phosphorimager is a replacement for autoradiography. The instrument uses imaging plates that are coated with a special phosphor that traps and stores radiation energy. The stored energy is stable until the plate is scanned with a laser beam which releases the energy as luminescence. The luminescent signal is detected by a photomultiplier and the data are ultimately stored as a digital signal. Sophisticated software running on a workstation allows the data to be displayed, analyzed, printed and stored. The principal advantage of a phosphorimager over traditional autoradiography is the wide dynamic range and increased sensitivity. This state of the art instrument will make a variety of experimental analyses more sensitive and facilitate quantitative analysis of the data collected. u ~ @ ^ G +G + P 4 ^ \ ?

9317489步行者A磷光成像仪是放射自显影的替代品。该仪器使用涂有特殊荧光粉的成像板，这种荧光粉可以捕获和存储辐射能量。储存的能量是稳定的，直到用激光束扫描平板，激光将能量释放为发光。发光信号由光电倍增管检测，数据最终存储为数字信号。运行在工作站上的复杂软件允许显示、分析、打印和存储数据。与传统放射自显影相比，磷成像仪的主要优势是动态范围宽，灵敏度高。这种最先进的仪器将使各种实验分析更加灵敏，并有助于对收集的数据进行定量分析。U~@^G+G+P 4^\？R U V^_4 u+~#w~t^U V^v TD 9317489步行者磷光成像仪是放射自显影的替代品。该仪器使用的成像板上涂有F**B Times新罗马符号&amp；Arial 1 Courier 0 MS LineDraw*h 5b e5b e=抽象沙漠国王，BIR沙漠国王，BIR沙漠国王
