| 520 | |a"The Sediment Survey program includes the collection of "bed material" samples that are analyzed for particle size distribution. The present method of oven-drying requires vigorous grinding with a mortar and pestle to disaggregate the particles. The adaptation of the freeze dryer reduces this grinding time considerably. This report evaluates the freeze dryer or lyophilization method of disaggregating sands, silts and clays for particle size analysis and compares it with the oven-dried method presently used in the Sediment Laboratories of the Water Survey of Canada"--Abstract, p. v. |
