High Quality High Efficiency WQF-520A FTIR Spectrometer

Short Description:

  • New type cube-corner Michelson interferometer features smaller size and more compact structure, providing higher stability and less sensitive to vibrations and thermal variations than conventional Michelson interferometer.
  • Fully sealed damp and dust- proof interferometer, adopting high performance, long lifetime sealing material and desiccator, ensures higher adaptability to the environment and increases accuracy and reliability in operation. Viewable window for silica gel enables easy observation and replacement.
  • Isolated IR source and large space heat dissipation chamber design provides higher thermal stability. Stable interference is obtained without the need of dynamic adjustment.
  • High intensity IR source adopts a reflex sphere to obtain even and stable IR radiation.

Diffuse/Specular Reflectance Accessory
It is a versatile diffuse reflectance and specular reflectance accessory. Diffuse reflection mode is used for transparent and powder sample analysis. Specular reflection mode is for measuring smooth reflective surface and coating surface.

  • High light throughput
  • Easy operation, no internal adjustment needed
  • Optical aberration compensation
  • Small light spot, able to measure micro samples
  • Variable angle of incidence
  • Fast change of powder cup

Horizontal ATR /Variable Angle ATR (30°~ 60°)
Horizontal ATR is suitable for the analysis of rubber, viscous liquid, large surface sample and pliable solids etc. Variable angle ATR is used for measurement of films, painting (coating) layers and gels etc.

  • Easy installation and operation
  • High light throughput
  • Variable depth of IR penetration

IR Microscope

  • Micro samples analysis, minimum sample size: 100µm (DTGS detector) and 20µm (MCT detector)
  • Non-destructive sample analysis
  • Translucent sample analysis
  • Two measurement methods: transmission and reflection
  • Easy sample preparation

Single Reflection ATR
It provides high throughput when measuring materials with high absorption, such as polymer, rubber, lacquer, fiber etc.

  • High throughput
  • Easy operation and high analytical efficiency
  • ZnSe, Diamond, AMTIR, Ge and Si crystal plate can be selected according to application.
