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.
