许多土壤科学实验室使用吸管法进行粒度分析。然而，在特定深度处对悬浮液进行采样仍然是麻烦和耗时的。本文提出了一种方法，其中土壤悬浮液（粘土和粉砂）采样更快，更容易与水平插入悬浮液通过隔膜的注射器。并将新的注射器法与吸管法进行了比较。这两种方法同样准确，但注射器法的优点是更容易处理和更省时。这使得它特别适合于系列分析。
Grain size analysis is performed in many soil science laboratories using the pipet method. However, it is still troublesome and time consuming to sample a suspension at a particular depth. In this paper a method is presented in which soil suspensions (clay and silt) were sampled faster and more easily with a syringe inserted horizontally into the suspension through septa. The new syringe method was compared with the pipet method. Both methods were equally accurate but the syringe method has the advantage of being easier to handle and more time efficient. This makes it especially suitable for series analysis.
