Abstract
Indeterminate error of dilution with pipette and flask is studied base d on experiments, statistics, Monte Carlo simulation and probability t heory. Equations which describe the error of sample concentration afte r the dilution are probabilistically derived and verified experimental ly and statistically. The uncertainty structure of dilution is shown t o be different for the pipette-pipette dilution and the pipette-flask dilution. The theory for dilution error developed here will be a basis to predict the precision of some chemical analyses such as the intern al standard method in chromatography.
