Product Introduction:

The EC2000 GPC gel chromatography workstation is a special data processing function module for gel chromatography loaded on the platform of the EC2000 chromatography data processing workstation of Yilite Company. EC2000 GPC gel chromatography workstation has the following basic functions and features:

Calibration of standard samples
Calculate the calibration curve based on the number average molecular weight or weight average molecular weight or (and) dispersion coefficient of monodisperse or widely distributed standard samples, and the Mark Houwink constant (k and a) of narrow or unknown samples; Correct the results of multiple parallel injections of any number of standard samples and each standard sample to eliminate experimental errors; Select a regression correction curve for linear, quadratic, or cubic equations, use the least squares method to fit and automatically calculate the standard deviation and correlation coefficient; At the same time, obtaining the average molecular weight and error of the standard sample calculated by the fitted curve can intuitively judge the fitting result and make corrections at any time.

Molecular weight determination
Calculate various statistical molecular weights and dispersion indices of polymer substances, such as number average molecular weight, weight average molecular weight, Z-average molecular weight, Z+1 average molecular weight, viscosity average molecular weight, etc., based on the molecular weight correction curve and peak slice areaWait; By setting the slicing method, it is possible to calculate and analyze any range in the spectrum.

molecular weight distribution
Calculate the integral molecular weight distribution curve (cumulative weight fraction molecular weight distribution) and the differential molecular weight distribution curve (including differential cumulative molecular number fraction molecular weight and differential cumulative weight fraction molecular weight distribution); The distribution map can be displayed in three ways: molecular weight, molecular weight logarithm, and logarithmic scale coordinate system.

Output results and printing
Output gel chromatographic separation spectrum, calibration curve, integral molecular weight distribution curve, differential cumulative molecular number fraction molecular weight, differential cumulative weight fraction molecular weight distribution curve, various molecular weights and related parameter calculation results; According to the experimental purpose, peak cutting method can be used to select local or full range for calculation, output, and printing of results; The molecular weight calculation result table, molecular weight distribution chart (including integral distribution chart and differential distribution chart), molecular weight distribution data, calibration curve, and standard molecular weight data can be sent to the shear plate and processed using relevant software (such as Word, EXCEL, etc.), which has great flexibility.
