Abstract
Effluent from an LC is passed through a thermospray nozzle which flash vaporizes substantially all of the solvent while directing any sample components as a collimated beam onto a moving tape so that the various components form spots on the tape. The tape is moved along a path that intercepts the optical path of an FTIR spectrometer whereby IR energy from the spectrometer is passed through each sample component and is then spectrally analyzed. The tape can be wound up, stored, and later used for further analysis of the spots, as desired, in the FTIR spectrometer.
