Abstract:
A method of forming an array of powder samples arranged in predefined locations where all samples have a flat surface in a common plane comprising:(a) providing a monolithic block defining a main support section and a flat support section, said main support section having at least N depressions providing openings in a first surface of the main support section in predefined locations, where N is the number of samples in the array and N is at least two, said depressions in the form of perforations extending from a first surface of the main support section to a second surface defined by the main support section or the flat support section; (b) loading sample X in depression X of the main support section where X is an integer from 1 to N; (c) forming a flat surface of each sample where the flat surfaces are in a common plane by forcing the samples within the depressions against the fiat support section; (d) retaining the samples in position within the depressions using retaining means selected from the group consisting of a mechanical device, retaining material added to the depressions to fill additional volume, and a combination thereof; and (e) sufficiently exposing the fiat surfaces of the samples in the predefined locations for testing over a common plane by limiting the thickness of the flat support section.
