"Controlled Dispersion Flow Analysis Devices With Constant Flow For Flame Atomic Absorption Spectrometry"
Analusis 1994 Volume 22, Issue 9 Pages 453-457

Abstract: The characteristics were compared of two controlled-dispersion flow systems [cf., Sherwood etal,Analyst (London), 1985, 110, 493] for providing a stable non-segmented flow for introducing samples into the nebulizer of a flame AAS instrument. Sample consumption was reduced by up to a factor of three compared to a conventional FIA system and the sample volume was easily varied from 50-600 l by altering the pump timing. The two systems were applied to the determination of Cu, Fe, Ni and Sr in fluorite.
