Paper Abstract

The FT-IR spectra of liquid chromatographic fractions obtained using a flow-through liquid cell and an apparatus involving solvent-elimination and diffuse reflectance are compared. When working with complex mobile phase systems necessary for producing good LC separation, the diffuse reflectance method is capable of much higher sensitivity than the flow-cell technique. Examples of the sensitivity levels achievable with the diffuse reflectance method are presented.
