Introduction:
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. TJ270-30A is an important tool in analytical laboratories.

It 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
