Size Exclusion/Gel Permeation Chromatography
Molecular Weight Software
Accurate
SEC/GPC Software that is Easy to Use
Now
there is a full-featured Size Exclusion Chromatography software
package that is fully integrated with Chrom Perfect® for Windows.
SEC provides a wide variety of calibrations and reports and produces
accurate and reproducible measurements of molecular weight.
Three Modes of Operation
The software allows
you to retrieve a chromatogram collected by Chrom Perfect® and
produce SEC plots and reports interactively. It also allows you to
produce reports and plots interactively after each run or by batch
reprocessing a series of runs. The specifications for the reports
and plots come from an SEC method file that the chemist prepares
ahead of time.

With the SEC
software, you can display your report together with
the chromatogram and
weight distribution graphs. You can reset
baselines and
summation regions, and immediately see the effect
on the molecular
weight calculations. SEC enhances reproducibility
with a smoothing
algorithm on the baseline. You can include
negative peaks in the
calculations or exclude them.
Transfer Plots and Reports to Other Software
The software can leave SEC results in ASCII
files for transfer to other software packages such as EXCEL, Lotus
1-2-3, or a word processor. It can also leave the plot in a Windows®
metafile or bitmap file for transfer to your word processor or
desktop publishing software.
SEC Calibration
SEC
supports a wide variety of calibrations, including:
narrow standard
broad standard
universal calibration
The software fits the
calibration curve with a polynomial up to degree 5.
The software can
compensate for drift with internal standards.
SEC Reporting
The format of the
report is fully configurable through an SEC method file.
-
The software
fully documents the source of the data and calibration. It gives
you over 200 characters of user-defined sample identification.
-
You can use
interactive graphics to set the start and stop positions of the
baseline and processing ranges. The software computes the
molecular weight
-
range that
corresponds to these points.
-
The software can
show the amount of polymer above or below specified bounds.
-
The software
provides six types of molecular weight calculations.
You can specify the
slice width for the table that shows percent off versus retention
time.
The software will
detect the peaks in the SEC chromatogram, and provide molecular
weight summations for each peak.
