RAE Systems Receives Patent for Corona Discharge Ionization Gas Detector; CDRAE Uses New Sensor to Detect VOCs.Business Editors/High-Tech Writers RAE Systems Inc. (OTCBB OTCBB See OTC Bulletin Board (OTCBB). :RAEE.OB), a Gas Detection and Smart Sensing Network solution provider for security, environmental and safety monitoring, today received the final print of patent US 6,333,632, titled "Alternating Current Discharge Ionization Detector ÃA discharge ionization detector (DID) is a type of detector used in gas chromatography. Principle A DID is an ion detector which uses a high-voltage electric discharge to produce ions. ." This is RAE Systems' seventh gas detection patent. The CDRAE, the first RAE Systems product to utilize this patented technology, is a portable gas monitor for detecting a broad range of Volatile Organic Compounds (VOC (Vertical Online Community) See vertical portal. ) with ionization potentials up to 11.7 electron volts. All VOCs are flammable and many are toxic. The inventors, Wenjun Yang, Ph.D., senior chemist and Peter Hsi, Ph.D., vice president and chief technology officer, created this sensor to provide a safer alternative to flame ionization detectors (FID), which use perilous hydrogen as a working gas. This new corona discharge ionization detector also has better long term stability than photo-ionization detectors (PID (1) (Process IDentifier) A temporary number assigned by the operating system to a process or service. (2) (Proportional-Integral-Derivative) The most common control methodology in process control. ) when used to detect high ionization ionization: see ion. ionization Process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules (ions) by the removal or addition of negatively charged electrons. energy chemical with ionization potentials greater than 10.6 electron volts. Applications for this new gas detection technology and the CDRAE include chlorinated chlorinated /chlo·ri·nat·ed/ (klor´i-nat?ed) treated or charged with chlorine. chlorinated charged with chlorine. chlorinated acids some, e.g. solvents, gas leak detection Gas leak detection can be done by use of various methods. Traditionally methods include Catalytic/IR Point Sensors and IR Open Path Sensors, more recent detection methods include Ultrasonic Gas Leak Detectors. , hazardous material response, landfill monitoring, industrial hygiene, hazardous waste monitoring, soil contamination monitoring, water contamination detection, manufacturing process monitoring and refinery facility surveys. The CDRAE is available now for $8,700 to $10,100 in both portable and fixed mount configurations.
