TJ270-30(A)
Quantity:
Infrared Spectrophotometer TJ270-30(A)
Application:
The TJ270-30 (A) Infrared Spectrophotometer can be used to record either IR absorption or (with accessories) IR reflection spectra in the range of 4000 cm-1 to 400 cm-1 (wavelengths from 2.5 m to 25 m).  The user can do qualitative or quantitative analysis on the measured sample using either the stored spectrum or the plotted spectrum. It is a useful tool for petrology, the chemical industry, medical work, food safety, the paper industry, environmental monitoring, the semiconductor industry, etc., for material structure analysis.
