I. Application of The Instrument

HZHW-10 Double-Beam Infrared  Spectrophotometer can record material in the 4000-400cm- 1  range of the infrared absorption spectrum or spectral reflectance. According to the recorded spectrum of the measured analysising the qualitative and the quantitative. It is an important tool in Petroleum, chemical, medicine, health, food, paper making,  environmental monitoring  and  semiconductor manufacturing and other industries material structure analysis.
