Abstract

Multiple samples are prepared in slurry form and deposited through a funnel plate by a multiprobe liquid handler into an array of inserts situated in openings in a housing. Each insert has a recess that extends through the insert body and a filter disc situated in the recess to support the sample. The filter is held in place by an annular part which defines a channel providing access to the filter through the lower portion of the recess. A pressure differential is created across each of the filters by attaching a vacuum manifold to the bottom of the housing to simultaneously remove the liquid from each of the samples, leaving the samples in powder form. The housing is then placed in the X-ray diffractometer for sequential analysis of each of the samples, while the samples are situated in the inserts.
