Features of RSpak DE Series (1) (Comparison with ODS Column)
RSpak
DE-413 is a polymer-based column for reversed phase
chromatography and has unique separation characteristics and superior chemical stability. The column can be used under the same
conditions as those for ODS columns. Here, lactitol and erythritol were separated by DE-413, though they could not be separated
by a ODS column from other manufacturer. The polarity of the packing material of DE-413 is close to that of ODS columns, however,
the separation characteristics of DE-413 is a little different from that of ODS columns and some substances which cannot be
separated by ODS columns can be separated by DE-413.
