[New applications of FTIR micro-spectroscopy in the field of forensic science].

The new applications of FTIR micro-spectroscopy in the field of forensic science are presented, and the process and results of infrared spectra measurements of many kinds of samples, such as paint, fiber, dye, plastic, rubber, ink and drug have been discussed in detail, including two real cases. Various sampling accessories (Diamond cell, Attenuated total reflection and Micro manipulator system) and different determination modes (transmission and reflectance) are used according to the properties of samples.
