Zur Bestimmung des D₂O-Gehaltes in schwerem Wasser nach der Schwimmer-Methode

Abstract

For the evaluation of float measurements all individual steps of the calculations are comprised under the expression of “precise float formula”. From this simplified approximations can be deduced. Their errors are estimated under little restraining conditions. The rather simple “difference formula” in the range of high D₂O-concentration together with a density scale for pure D₂O gained by interpolation suffice for most practical purposes. This is proved by numerical comparing with the precise formula.
