Abstract
A high thermal conductivity combustion cone in combination with a chemical analysis instrument is disclosed. The cone functions to capture and rapidly volatilize a liquid sample drop injected into the instrument. The volatilized components are then reacted with a feed or carrier gas in the presence of a heated catalyst bed. Changes in the reacted gas are detected by a sensor and quantitatively analyzed as an indicator of the chemical nature of the sample.
