Summary
A simplified method has been developed to determine molecular weight by using a constant volume of solvent and using polystyrene as a standard, molecular weights up to 51000 can be obtained with less than 2% error from a graph. If calculated by computer, 5% error is the maximum.
Zusammenfassung
Ein vereinfachtes Verfahren unter Verwendung eines konstanten Lösungsmittelvolumens sowie von Polystrol als Standardsubstanz ermöglicht die Bestimmung von Molekulargewichten bis zu 51 000 mit einer Fehlerbreite von 2% an Hand einer Eichkurve. Bei Berechnung mit einem Computer ist die maximale Fehlerbreite 5%.
