IR-1 workstation is a Digilabs FTS-3000 rapid scanning FTIR that is configurable in either the Near-Infrared, Mid-Infrared or Far-Infrared. It is normally configured for Mid-Infrared work. Measurements can be made in transmission, reflection, and attenuated total reflection (ATR) with this instrument. Methodologies that are most often conducted with this instrument are routine sample measurement, cryogenic work and laser photolysis additionally this instrument is used for training, and class instruction. The IR-1 workstation can also be fitted with a wide range of FTIR accessories to provide additional capabilities.
