This is a screenshot of the OmniSEC profile of dextran. We offer a set of broad Dextran standards for light scattering and triple detection. The run conditions are detailed in the table below.
|Flow Rate [mL/min]||0.700|
|Column Set||2 x A6000M|
|Column Temp (°C)||35.0|
|Injection volume μL||100.0|
|Mw Weight Average [Da]||73,123
|Sample dn/dc [mL/g]||0.137|
|Sample IV [dL/g]||0.236|
Dextran is a typical polysaccharide and chromatographs very well. This dextran has a broad polydispersity index PDI = Mw/Mn value of 1.38. It is typically used as a system suitability sample for aqueous polymer applications, and often also a good choice for system calibration.
