Abstract Scintillation flow cells provide a convenient means of monitoring column effluents for radioactively labeled compounds. The use of flow cells to monitor effluents containing 3H, 14C, and other β-emitting isotopes is well established (1) and such cells are readily available as accessories for use with liquid scintillation counters. β-Flow cells have occasionally been used to monitor γ emitters [e.g., Martin et al. (2)] but the counting efficiency is extremely low even for weak γ emitters such as 75Se, due to the limited mass of scintillant available to absorb the radiation. Spencer et al. (3) described a simple γ flow cell consisting of a coiled polyethylene tube inserted in to the well crystal of a γ counter, but no information on counting efficiency was given. Although spiral plastic γ cells have been manufactured commercially (e.g., Nuclear Enterprises Ltd., NE7021 1 N.B.: Recent advice from Nuclear Enterprises Ltd., indicates that this γ flow cell is now out of production.) they are not offered as a standard accessory for most common makes of γ counter and do not appear to be readily available from commercial sources. This communication describes a simple, low cost γ flow cell constructed for use in a study on selenium transport in higher plants, which involved the separation of 75Se-labeled constituents in a large number of samples of xylem sap.
