What is the best way to make a microscopic comparison of paint chips

The best way for the microscopic comparison of paint chips is the standard infrared spectroscopy technique.

Explanation:

The hit and run road accidents often leave paint chips with which the forensic investigation is conducted and the complete incident is recalled. The paint chips are actually multi-layered materials with several coats of paints.

The best way to make a microscopic comparison of paint chips, infrared microscopes are used which provide spectra for each of the existing layer.

There are three main sampling techniques in the infrared spectroscopy such as Transmission, Attenuated Total Reflectance (ATR) and the specular reflectance. With this technique, scientists can better judge the consequences of the incident and provide better proofs of the crime.
