Fourier Transform Infrared Spectrophotometer (FTIR)

An FTIR is used to detect specified compounds and their quantities in a specimen.  It can be used for detecting both organic and inorganic chemicals.  This instrument is valuable to forensic scientists for discovering compounds you can't see with he naked eye on evidence.  Its sensitivity and versatility is of great importance to forensic scientists for discovering compounds from evidence such as blood, paints, polymer coatings, drugs, and organic/inorganic contaminants.

Chemical Fume Hoods

These are important to forensic scientists as a means of protecting them, the product/experiment, and/or the environment from hazardous or noxious fumes, vapours or dusts.  They ventilate the air instead the fume hood and either expel it or recirculate the cleaned air back into the room.
