If the chromatography software you already have
can export chromatogram file of AIA format (with suffix of *.cdf),
then no extra analog/digital acquisition hardware is needed.
According to the RI peak and the UV peak of a
standard sample with the known Mn and the known time lap between
the two peaks, a three order polynomial standard curve of
molecular weight vs. time is obtained.
Mw, Mn, percentage of substance with Mw<8000,
and the curve of cumulated molecular weight distribution are
automatically generated in the user report.
Peak slices details can also be generated in the
