Chemometrics, an advanced field of chemistry, utilizes the application of mathematics and statistics to clinical information. One example of chemometrics is pyrolysis mass spectrometry, in which an unidentified material is fixed to a metal strip and heated to a specific temperature. At this temperature, the electrostatic bonds holding the atoms together break. Using the light components given off by the atoms, the mass spectrometer creates a chemical profile, or chemical fingerprint. With these statistics, the chemist is able to identify the material.
