Glass nebulizer interface for capillary electrophoresis–Fourier transform infrared spectrometry

A capillary electrophoresis system has been successfully interfaced to a Fourier transform infrared spectrometer. The design of the interface is a custom-designed glass microconcentric nebulizer. Typical deposit characteristics include reproducible circular deposits of uniform thickness that lack any splatter as found in earlier designs. Interface performance is demonstrated in that there is no loss of electrical current during operation and spectra of analytes can be readily produced. Furthermore, it has been shown that the interface maintains the plug flow characteristic of capillary electrophoresis.
