Miniature elutriator

In the miniature elutriator [20] a high velocity jet blows downwards into a thimble at the base of the elutriator tube. The tube is much smaller than that of other elutriators being 14 in long and 1 in diameter. 

This part covers air elutriation methods, such as the Gonell, the Roller (modified ASTM), and the miniature elutriation methods. As these are rarely, if ever, used for particle size distribution determination nowadays, it is likely that this Standard will be withdrawn.
