Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.
[0021] The present invention learns from and improves the differential algorithm of the differential GC / MS method proposed by Ghosh and Anderegg, and applies it to the analysis of spectrogram data of the HPLC-AFS system. The difference algorithm uses vector thinking, which is carried out in two steps:
[0022] The first step is to denoise and fit the original fluorescence data collected by the HPLC-HG-AFS system, and store the preprocessed data in a vector S, S=[s 1 ,s 2 ,...s n ]. Then, subtract two adjacent data points in S, and store the positive and negative difference values in two vectors U and V respectively, U=[u 1 ,u 2 ,...,u n ], V=[v 1 ,v 2 ,...,v n ]. Among them, U is used to store the positive difference, and V is used to store the negative ...
