Phenogel size exclusion columns for gel permeation chromatography (GPC) are composed of highly cross-linked styrene-divinylbenzene (SDVB) and achieve high resolution and tight linear calibration curves. Phenogel GPC columns are available in seven different pore sizes, ranging from 50 Å to 106 Å; and a linear bed configuration. Pore size distribution and pore volume are closely ...
MZ-Gel SDplus is a highly cross linked poly(styrene-divinylbezene)-copolymer from MZ-Analysentechnik GmbH especially designed for organic eluents. It is available with porosities from 100 Å to 1,000,000 Å and linear according to a molecular weight range up to 10 million D. Typically, our columns are packed, tested and shipped in THF (other specifications on request). Please consult ...
.• Fully configured packages include reverse-phase C-18 column, solvent delivery system, syringe and detector.• Variable wavelength systems give hi-resolution selectivity [5nm] from 190- 360nm (D2) and 360-800nm (Tungsten).• Wide selection of reverse-phase (C-18, C-8, Amino, Cyano, Phenyl), normal (SiO2 & Al203) and GPC columns available.• ...
The BI-MwA has the highest performance/price ratio of any light scattering detector used for molecular weight determination. Eliminate SEC/GPC column calibration and improve data quality. Rapidly reduce uncertainty with no assumptions required and true extrapolation to zero angle. ...
During the analysis, the GPC column separates the polymer molecules on the basis of their size in solution, and the detector determines the amount of material eluting from the column as a function of retention time. ...
For this purpose, GPC-IR® was designed with a dedicated and precise (0.01ºC) oven to hold the columns only. ...
