SYSTEMS AND METHODS FOR PREPARING SAMPLES FOR CHEMICAL ANALYSIS USING A COOLED DIGESTION ZONE

摘要

An apparatus for preparing samples for chemical analysis includes a container receptacle for receiving a sample container having a crucible portion and an expansion portion. The container receptacle includes a heating compartment and a cooling compartment spaced apart from the heating compartment. The heating compartment is shaped to receive the crucible portion of the sample container, and the cooling compartment is shaped to receive the expansion portion of the sample container. The apparatus also includes a heating mechanism for heating the sample within the crucible portion of the sample container, a first cooling mechanism for cooling the expansion portion of the sample container, and a second cooling mechanism for cooling the crucible portion of the sample container.
