Identification of Contaminants Using Spectroscopy
The ability of the infrared analysis technique to deal with small particles makes it a powerful tool for the study of environmental and industrial contaminants.
Contaminants on solid objects can be studied by removing them from their substrates and measuring transmission, or they can be studied on the substrate (in situ) by reflectance. Contaminant particles in air or liquids can be trapped on suitable filter media and studied by either method.
One of the advantages of the infrared analysis technique is the ability to record the spectra of unknown samples with little or no sample preparation thus providing a nondestructive procedure which preserves the sample for additional types of analysis if required.
