Hydrostatic buoyancy alternative correction for weighing using high-resolution single-pan balances

Abstract

In this work we compare some methods of buoyancy corrections applied to sample weighing that require a high accuracy results. We also established and disseminate the fundamentals for a better understanding of this phenomenon. An alternative approach was applied to find a buoyancy correction equation adapted to single-pan balances. The results show a good compatibility between two of these buoyancy corrections. The approach advantage is to keep the mathematical formalism adapted to the single-pan balance measurement procedure, dislike the others methods that developed its formalism based in the equations adapted to the double-pan balances.
