• Abstract:

  Compendial methods for molecular weight distribution (MWD) of dextrans are based on double standard approach. Narrow standards are used for calibration and broad standard should be used for system suitability test. Prescribed limits of system suitability are broad and therefore may cause large uncertainty of results. And results strongly depend on ..
