Essential oil samples are transported to a manufacturing facility for filling. Before being released into the facility, the essential oil “batch” is held in quarantine while additional quality tests are performed. Those tests include an FTIR Scan which, similar to GC/MS testing, is also an analysis of material composition. In an FTIR Scan, a light is shown at the material sample and the amount of light absorbed by the chemical constituents of the sample is measured. Results are then compared against a historical database to ensure adherence to composition standards.
