[Study on chromatographic peak identification by means of peak shape analysis]

A new method for chromatographic peak identification by means of peak shape analysis is presented in this paper. Directly measurable parameters, i.e. peak width and asymmetry factor are first utilized for peak shape analysis. It is showed from theoretical and experimental results that for a component having almost the same retention time with the standard, an overlapped peak can be obtained by injecting the mixture of analyte and standard. In comparing the peak shape of overlapped peak with the standard one, the component can be identified whether it is the same with the standard or not.
