      <subfield code="a">Weighing of filters is of fundamental importance in numerous annalysis techniques, yet the errors associated with such weighings are not generally appreciated. The reproducibility achievable in weighing of filters on different balances, and under different conditions, has been experimentally determined. The implications of these findings for the detection limit of gravimetric filter analysis are discussed</subfield>
