Abstract
Methods and devices for inline sampling of a bulk material, such as a powder, are provided. The material's bulk density can be determined from samples drawn using methods and devices described herein. One embodiment of a method of sampling a material allows the material to flow through a sampling compartment, closes off the flow of material below the sampling compartment, builds up a column of material through the sampling compartment, shifts the sampling compartment to remove a slice of material in the column, and places the slice of material into a sample container. A device for sampling a material is provided in another embodiment. The device includes an inlet, an outlet aligned with the inlet, and a sample collector. The sample collector can include at least one through hole and be configured to move such that the at least one through hole can be moved into and out of alignment with the inlet and the outlet.
