A powder capsule loading system and apparatus for preparing and loading a gelatin capsule with a powder product for testing of the product in a magnetometer. The system includes a gelatin capsule which is readily available, such as those used in the pharmaceutical industry, and a sample tool including a handle section and a cup section which includes an aperture sized to receive part of a capsule portion and holds the capsule portion therein by friction fit. Initially, a top portion of the capsule and a bottom portion of the capsule are each received and held on different sample tools. The capsule portions received within the sample tools are dipped into a sample container of powder product to fill the respective portions with the powder product, followed by assembly of the capsule. The assembled capsule containing a substantially predetermined amount of powder therein is then weighed. If the weighed capsule falls within a predetermined range, the sample is then loaded into an adapter on a vibration sample magnetometer designed for receiving the capsule and subsequently tested for magnetic properties. If the sample falls out of the predetermined weight range, the sample is disposed of and the procedure repeats until a satisfactory testing sample is prepared.

An apparatus and method for determining both the breakdown voltage and the conductivity of a particulate material, such as a developer material, is provided. In a preferred embodiment, the apparatus for determining breakdown voltage comprises a breakdown cell for storing a preselected quantity of the particulate material and a voltage breakdown ('VB') autometer, the VB autometer being adapted to apply a first voltage across at least portions of the preselected quantity of the particulate material. The VB autometer is capable of progressively varying the magnitude of the first voltage. A measuring circuit, for measuring a second voltage, is coupled to the voltage breakdown cell. When the second voltage substantially equals a preselected reference voltage, the first voltage substantially equals the breakdown voltage of the particulate material.
