The data station calculates number average molecular weight (Mn), weight average molecular weight (Mw), Z average molecular weight(Mz), Mv and Polydispersity.

The data system uses the first to 5th polynomial equation to fit the regression curve. It is more realistic on GPC analysis.

※ The data station uses the following methods to perform GPC calibration:

1. Directly input the coefficients to set up the calibration curve.

2. Load the calibration chromatograms and then integrate the area for building calibration curve.

3. Load retention time and molecular weight to build the calibration curve.

The user has the option to decide where is the initial point for integration, if it is necessary to convert a negative peak, the initial and end point of molecular weight calculation.

The data station displays differential curve, calibration curve, and position of Mn, Mw, Mz and the position of an integrated curve as well as the GPC chromatogram.

The data system display each slice of the GPC integration area including retention time, slice area, % area, cumulative % area, Mn, Mw and Mz. This information will be displayed along with the arrow point of the mouse.

The system also provides several function to plot the dW/d(LogM) vs Log M. The Y axis can be Int M.W. %. It also plots Area % vs logM. The Y axis can also be Int M.W. % too.

The slicing information of GPC can be converted to DDE format and be used under the Excel environment. It also can store the information in a text file.

※The system is capable of storing the instrument parameters and lists them on the final report.

※Batch GPC calculation and report printing is also available in the system.

※The data system allows the user to display several GPC on a graph for comparison reason.
