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.
