Apparatus and Method for Ultra-Sensitive trace Analysis (open access)

Apparatus and Method for Ultra-Sensitive trace Analysis

An apparatus and method for conducting ultra-sensitive trace element and isotope analysis. The apparatus injects a sample through a fine nozzle to form an atomic beam. A DC discharge is used to elevate select atoms to a metastable energy level. These atoms are then acted on by a laser oriented orthogonally to the beam path to reduce the traverse velocity and to decrease the divergence angle of the beam. The beam then enters a Zeeman slower where a counter-propagating laser beam acts to slow the atoms down. Then select atoms are captured in a magneto-optical trap where they undergo fluorescence. A portion of the scattered photons are imaged onto a photo-detector, and the results analyzed to detect the presence of single atoms of the specific trace elements.

Fail Save Shut Off Valve for Filtering Systems Employing Candle Filters (open access)

Fail Save Shut Off Valve for Filtering Systems Employing Candle Filters

The invention relates to an apparatus that acts as a fail save shut off valve. More specifically, the invention relates to a fail save shut off valve that allows fluid flow during normal operational conditions, but prevents the flow of fluids in the event of system failure upstream that causes over-pressurization. The present invention is particularly well suited for use in conjunction with hot gas filtering systems, which utilize ceramic candle filters. Used in such a hot gas system the present invention stops the flow of hot gas and prevents any particulate laden gas from entering the clean side of the system.
