Thief sampling probe

摘要

A sample thief comprising: an outer hollow rod with an open end; a piston with a plunger end inserted within the outer hollow rod; and the outer hollow rod having an adjustable means. The thief operates by inserting the thief into a blend to be sampled just above the area of the blend to be sampled; adjusting the plunger so that a cavity greater than the desired sample size is created; compacting the sample into the thief; removing the thief from the blend; ejecting the excess sample to a predetermined point; and collecting the sample.
