Leak Detection in Ultra-High Purity Gas Distribution Systems

Delta F Corporationce analyzer has a sensitivity of <0.1 ppb and an LDL of <0.2 ppb. The analyzer uses an extension of the Delta F Non-Depleting Coulometric sensor technology. The sensor uses carbon-based electrodes which do not undergo chemical change to make measurements. The proprietary, inert carbon-based electrodes are driven by an external 1.3 VDC potential and extremely stable. These sensors use a consumable cadmium anode electrode, which itself develops the electrochemical potential needed to drive the O2 reactions, but it is inherently much less stable then the Delta F electrode.

Delta F includes an exclusive system to Delta F Corporationce sensor for Electrolyte Conditioning. The Stablex System removes dissolved oxygen from the electrolyte without the need for sparging, or otherwise bubbling sample or zero gas through the electrolyte. Sparging (bubbles) introduces electrochemical noise to the sensor output preventing clean and predictable low detection levels. To ensure long term zero stability, the sensor also employs a patented technology to protect the sensor from the inevitable ionic impurities in the electrolyte.

The Hand-Carry Portable configuration of the analyzer makes it an ideal tool for investigative, spot-checking measurements. The analyzer can be configured for Hand-Carry Portable use by selecting the Supplemental NICAD Battery Power, Isolation Valves, and On-Board Calibration options.
