Some of the problems commonly found in high-performance liquid chromatography (HPLC)/Fourier transform infrared spectrometry (FTIR) can be alleviated through the use of microbore HPLC columns. An interface based on a solvent elimination technique and utilizing the microsampling capability of diffuse reflectance (DR) FTIR has been designed for use with microbore HPLC. Detection limits achieved with the interface are about an order of magnitude lower than those previously reported. Several different microbore columns were studied and the relative advantages and disadvantages of each, with respect to the interface, are discussed. (Copyright (c) 1985 American Chemical Society.)
