CHEM4-UV-FIBER分光光度计
CHEM4-UV-FIBER Spectrophotometer
商品货号:ECS001272
商品品牌:ocean optics
详细介绍

CHEM4-UV-FIBER分光光度计系统可覆盖200-885nm的光谱范围,光学分辨率为1.0 nm(FWHM),可在1秒内捕获3648像素的数据。它是进行相对光强和辐射测量的理想工具。

CHEM4-UV-FIBER分光光度计系统由USB4000光谱仪和相关附件组成,来进行吸光度测量。这些可进行吸收测量的附件包括ISS-UV-VIS集成取样系统、一个300μm的抭负感作用光纤与一个1-cm样品支架。

基于光纤的系统的优越性在于其灵活性。根据测量的要求,还可以添加反射型光纤探头和浸入型光纤探头配件。

产品特点:

  • 全集成、预配置的系统,测量波长范围200-885nm,光学分辨率为1.0 nm(FWHM)
  • 体积小,适用于实验室和教学使用
  • 灵活的光纤的系统,可方便地添加配件
  • 集成了氘-钨卤组合式光源和样品支架
  • 吸光率小至0.01
  • 使用USB 2.0接头,可快速将光谱仪与计算机相连
