| Description |
Infrared spectroscopy is applied in the petrochemical industry to determine and quantify the chemical functional groups present in petroleum products. Infrared spectroscopy is sometimes referred to as molecular spectroscopy because it identifies the molecules in a sample... |
... as opposed to emission spectroscopy that identifies the elements in a sample. An IR analysis of an oil sample provides a fingerprint based on absorbed frequencies of infrared radiation that are unique to each chemical functional group. |
