摘要：

An automatic balance has been designed, constructed, and tested for continuous determination of the weight of the eluent in chromatography. This balance is considerably more precise than the frequently used automatic siphons. As the elution volume for any molecular species is independent of flow rate over a considerable range, the balance can be used with relatively inexpensive pumps, and thus highly precise constant volume pumps are not required.
