The present disclosure provides a high-temperature thermal pellet composition that maintains structural rigidity up to a transition temperature of about 240° C. The composition comprises at least one organic compound (e.g., triptycene or 1-aminoanthroquinone). The pellet can be disposed in a housing of a thermally-actuated, current cutoff device, such as a high-temperature thermal cutoff device (HTTCO). Also provided are material systems, which include the pellet composition and a high-temperature seal that provides substantial sealing up to at least the transition temperature. Methods of making such high-temperature pellet compositions and incorporating them into a thermally-actuated, current cutoff device are also provided.

This application discloses a liquid chromatography system which can be operated in a batch or a continuous mode. The system consists of the chromatographic column, a reaction column wherein the substances previously separated are reacted to form a readily detected compound and a loop to recycle the mobile phase for reuse. A prime feature of this system is having the mobile phase contain a reactant which upon reaction with an unknown produces a readily detectable compound. This system is very suitable for plant quality control operations and is of considerable value in analyzing compounds having primary amine functionality.
