Restoration for Comprehensive Two-Dimensional Gas Chromatography [PDF]

2005 IEEE International Conference on Electro Information Technology, 2006
This paper develops an approach for restoration of data from comprehensive two-dimensional gas chromatography (GCtimesGC), a powerful new technology for chemical separations. GCtimesGC restoration is required to separate coeluting (i.e., overlapping) peaks. The GCtimesGC process is modeled as a two-dimensional linear, shift-variant system, based on the
