Abstract
Specimens of solid organic substances are decomposed by grinding the specimen to powder having particles of a size smaller than 75 microns, and then compressing the powder specimen. The compressed powder specimen is abraded by means of a scraper, and the abraded material metered out in predetermined amounts for incineration in an injector burner suitable for solids. In this manner, large quantities of specimen material which might contain elements that attack quartz glass can be incinerated without causing damage to the quartz glass burner. The apparatus for decomposing specimens of solid organic substances includes an injector burner that communicates with a powder processing and proportioning device through a flexible tube. The powder processing and proportioning device includes a specimen container for compressed powder, supported by a rotatable fixture to rotate the specimen container. A plug provided in the specimen container, but having radial clearance with respect to the container walls is held by a vertically movable fixture that furnishes movement to the plug along the axis of the specimen container. The scraper for abrading the powder specimen is attached to the plug and is thus movable toward the powder specimen while the container is being rotated. Abraded powder is drawn through the flexible tube to the burner.
