摘要: The invention provides a manual or automated method for eliminating minimizing retention time shifts in comprehensive two-dimensional gas chromatography (abbreviated GCxGC). Under nominal identical conditions (identical column-set specifications and GCxGC oven temperature programming), the allows one to reproduce times from another, another column outlet pressure another. A procedure is described manually automatically adjust head of primary (effective) secondary length compensate two- dimensional differences.
