Abstract
A heater for a cylindrical combustion tube employed in an analytical instrument includes a curved resistive heating element shaped to at least partially surround a cylindrical combustion tube in spaced relationship to the combustion tube. The resistive heating element includes a plurality of alternately staggered slots to define serpentine current flow paths for the resistive heating element. In a preferred embodiment the resistive heating element circumscribes at least 180° and preferably is generally U-shaped.
