    摘要: An elutriation apparatus which combines pressurized liquid nozzles (16A) and the low energy air nozzles (20) producing bubbles for flotation and separation of trace materials in a heterogeneous mixture of materials is described. Quantitative separation of trace evidence is achieved by the apparatus by a closed system of mechanical separations using the water and the air to isolate and deposit trace evidence on a fine mesh screen filter (17) submerged in the water (24) in a container (23). The method provides a rapid, quantitative and inexpensive method for detection of the evidence in soil samples.

    摘要: An elutriation apparatus which combines pressurized liquid jets and the low energy air bubble flotation for the separation is described. A manifolded set of multiple apparatus which increases operator efficiency is described. Quantitative separation of roots is achieved by the apparatus by a closed system of mechanical separations using water and air to isolate and deposit roots on a sieve submerged in the water. The method provides a rapid, quantitative and inexpensive method for measuring plant root responses to soil biological, chemical, and physical conditions.
