| Abstract: | Electron balance has been used to measure volume of solution put in by pipette of standard series in external standard method.It showed that precision of volume was improved hundredfold by electron balance method and thus the accuracy and linearity of the work curve was improved greatly.This method can be applied extensively to other laboratorial work which high accuracy of volume of solution put in by pipette is required. |
