LIIR-100 Dual-Beam Infrared Spectrophotometer


  • High quality thermocouple
  • Low stray light
  • High accuracy measurement
  • Simple structure with easy operation


Infrared spectroscopy is one of the most powerful techniques for identifying organic substances in organic and analytical chemistry. Infrared analysis can be both qualitative and quantitative. LIIR-100 is an important tool in analytical laboratories.

LIIR-100 Dual-Beam Infrared Spectrophotometer can be used to record the IR absorption and reflectance spectra of substances in the spectral range of 4000 ~ 400 cm-1. It is a powerful tool to analyze sample structures in the fields such as petroleum, chemical engineering, pharmacy, public health and environmental protection.

The Windows application software provides a user-friendly interface for the control of the spectrophotometer, data acquisition, and spectral analysis with functions listed below:

  • Spectral background baseline memory
  • Spectral background baseline correction
  • Spectral data smoothing operation
  • Spectral baseline slope correction
  • Spectral data differential operation
  • Spectral data arithmetic operation
  • Spectral data accumulating operation
  • Conversion of %T and Abs
  • Spectrum file management
  • Spectral peak search
  • Spectrum scale extension
  • Spectral absorption expansion
