A leak detector having a multi-stage concentrator, consisting of an array of heater elements which desorb analytes in a phased manner, in synch with the sample stream, to maximize sensitivity. The heater elements of the concentrator are coated with adsorber material on both sides of the heater elements, i.e., top and bottom sides, and have small anchor points to minimize power dissipation. The concentrated gas mixture output of the concentrator is electronically injected into a separator, which for separates the constituents of the detected analyte-fluid and recognizing the nature or source of the analyte.

Low power gas leak detector

Radiation detection tube having a glass envelope surrounding an anode and cathode, and having a further conductive surface surrounding a portion of the glass envelope in the region of the anode-cathode gap, the exterior conductor electrically coupled to the anode.

Radiation detection tube having spurious radiation shield
