Abstract
A device is disclosed for continuously making samples to be analyzed by known instruments such as an X-ray spectrometer. The device consists of means for depositing a crude composition and associated vitrifying agent together in a crucible in accordance with a predetermined ratio by weight. The crucible is heated to melt its contents into an homogenous liquid mixture which is cooled to form a solid beadlet to be analyzed. The beadlet is conveyed to the analyzing instrument. A computer measures the respective weights of the components of the crucible contained composition and non-conforming weight measurements result in the crucible being discarded and replaced by another.
