Abstract
A data manipulation method to make local chromatography data more usable and comparable to a reference. The method provides time axis correction to better match local data to a reference of the same time scale, time axis transformation to correspond more directly to a reference based on a different time scale, and response axis correction to better match a reference of the same or different response scale, while maintaining the original peak areas. The method may be used along or concurrently with other data manipulation technique to facilitate operations such as searching, matching, visual comparison, mathematical manipulation, and pattern recognition of chromatographic data.
