Spectrofluorometer for fluorescence research in electrochemical samples

Wide spectral range of research, high measurement sensitivity, light source intensity stabilization,

Description

The instrument is designed for fluorescence research in electrochemical samples (solid and liquid state). Enables to capture emissive and excitation spectrum of the sample. The sample may be illuminated with both: white and monochromatic light in 200 – 1200 nm range. The high efficient xenon lamp with innovative light intensity stabilization mode is used as a white light source in the system. In combination with Air Mass 1.5G Filter it can mimic the solar light spectrum. At the entrance of the sample chamber a monochromator is situated. Monochromator is equipped with automatically regulated input slit (where the light from xenon lamp source is directed) and output slit (from where the light is directed to the sample chamber entrance). Regulating the slits width enables to control the intensity of the incident light.

At the sample chamber output a second monochromator is situated. These monochromator catches the emission light from sample. At the output slit of the monochromator a photomultiplier connected to the controller and counter captures the photons of fluorescence. The whole fluorescence spectrum may  be precisely defined. The monochromator construction enables also to measure the total fluorescence light intensity (all the emissive wavelengths may be captured simultaneously). Filter wheels at the entrance and the output of the sample chamber can additionally reduce the stray light in the system.

It is possible to extend the spectrum range of the system up to 1800 nm using additional light source (halogen lamp) and additional photomultiplier.

The performance of the whole instrument is fully automated. The system operation is realized via dedicated, intuitive FotoGUI software.

Quantities measured by the instrument:

  • Excitation spectrum of the fluorescence,
  • Emissive spectrum of the fluorescence

    分光荧光计 用于电化学样品的荧光研究

    研究光谱范围广,测量灵敏度高,光源强度稳定、

    描述

    该仪器专为电化学样品(固态和液态)的荧光研究而设计。可捕捉样品的发射光谱和激发光谱。可使用 200 – 1200 nm 范围内的白光和单色光照射样品。高效氙灯具有创新的光强稳定模式,可用作系统中的白光光源。结合空气质量 1.5G 过滤器,它可以模拟太阳光光谱。在样品室的入口处有一个单色仪。单色仪配备有自动调节的输入狭缝(氙灯光源的光线从这里射入)和输出狭缝(光线从这里射入样品室入口)。调节狭缝宽度可以控制入射光的强度。

    在样品室的输出端安装有第二个单色仪。该单色仪可捕捉样品的发射光。在单色仪的输出狭缝处,一个与控制器和计数器相连的光电倍增管捕捉荧光光子。整个荧光光谱可以精确定义。单色仪的结构还可以测量总荧光强度(可同时捕捉所有发射波长)。样品室入口和出口处的滤光轮还可以减少系统中的杂散光。

     

    使用附加光源(卤素灯)和附加光电倍增管,可将系统的光谱范围扩展至 1800 纳米。

    整个仪器的性能完全自动化。系统操作通过专用的、直观的 FotoGUI 软件实现。
