采用比重计法进行颗粒大小分析所需的土壤分散时间从25分钟减少到仅2分钟。该方法包括将土壤浸泡在5%的Calgon溶液中15至20小时，然后用以约16，000 rpm的速度运行的土壤混合器将它们分散，2分钟。
The time required for dispersing soils for the hydrometer method of making particle size analyses was reduced from 25 minutes to only 2 minutes. The procedure consists of soaking the soils in a 5% Calgon solution for 15 to 20 hours and then dispersing them with a soil mixer running at a speed of about 16,000 r.p.m., for 2 minutes.
