Abstract
A method for improving the resolution of the chromatographic analysis based on deriving the point-spread function of a chromatographic column, i.e., a chromatogram of an individual compound, is described. A system of two functions—a chromatogram of the substance analyzed and a point-spread function of the chromatographic column—in combination with noise statistics enables the application of a RECOVERY signal-reconstruction software package in order to obtain a superresolution chromatogram. The superresolution means a better resolution than that determined by the width of the point-spread function. The proposed method is tested with a bovine serum albumin chromatography with the use of gel filtration. The resolution obtained exceeds that reached with the use of high-performance liquid chromatography (with a lower cost of the instrument system by a factor of 15–20).
