产品资料
岛津 SPD-20A紫外jianceq 是高效的、多功能的、紫外-可见光检测器，用于高效液相色谱分析。 SPD-20A使用氘灯作为光源，主要用于紫外线区域的分析。SPD-20AV结合了氖灯和卤钨灯。在SPD-20A中氘灯用于紫外线区域，而钨灯将分析能力扩展到可见光区。每个仪器都有三种测量模式-单波长、双波长和波长扫描。双波长模式同时检测两种波长，可以提供两种波长的色谱图，或是一个波长的色谱图和一个比率色谱图。在波长扫描模式中，测量出样品紫外吸收光谱。波长扫描模式旨在用于液流停止的情况。

参数规格
SPD-20A/20AV为UV-VIS检测器，可进行高灵敏度检测(噪声0.5 x10(-5) AU),并可提供宽的线性范围

(2.5AU)。SPD-20A:波长范围：190到700nm。SPD-20AV可设成一种模式：氘灯和钨灯同时点亮，在整个紫外和可见波长范围内实现高灵敏度的波长编程检测.波长范围是190到900nm.。
