Heppe Medical Chitosan is known for a huge variety of chitosan specifications and high quality products. To further satisfy our customers, we offer standard kits to simplify the analyis of chitosans.
Molecular weight standard kit
The molecular weight standard kit contains 10 different chitosans with several molecular weights of 18 to 530 kDa (Mp). With a size exclusion chromatography (SEC) our standards can be used to generate a calibration curve with an RI detector.
By using the chitosan standard kit the deviation of results between high end light scattering detector and RI can be reduced to less than 30%. Currently used standards like PEO/PEG (mentioned in USP), Pullulan or PVP causes deviations of up to 300 % in comparison to the absolute mesurements with a multi angle light scattering detector.
Use our reliable chitosan standards for an excellent research, outstanding pharmaceutical products and analysis. Now, order in our Shop!
