Die for preparation of fused salt discs for infrared spectroscopic analysis

Abstract

Abstract An improved die for use in casting of fused impregnated discs for infrared spectroscopic analysis, particularly where air and moisture are a problem. The improvement resides in the combination of a removably fastened base on a threaded die body and a single threaded plunger to fit the bore of the die. When the base is fastened to the die body, it acts as a supporting structure for an anvil seated at the bottom of the threaded die bore. In operation the impregnated salt to be pelleted is introduced into the threaded die bore onto the anvil positioned at the bottom of the bore, being secured in the bore by the fastened removable base. The plunger is thereafter screwed into the threaded bore until sufficient pressure is applied to produce a salt disc or pellet between the anvil and the plunger. The base is then removed and by turning the plunger a few more times, both the anvil and the fused disc are ejected from the die.
