An alcohol oxidase (AOD) immobilized gas-sensor (bio-sniffer) with stick-type configuration was developed for convenient analysis of ethanol vapor. The stick-type sniffer device was constructed in a sandwich configuration with a filter paper placed between carbon- and Ag/AgCl electrodes. The electrode-coated paper was shaped by knife into 2 mm-wide stick.

TDL Gas Analysers For selective gas analysers for one or two gases, TDL gas analysers make a cost-effective monitoring tool for low level monitoring of gases such as HCl and NH 3. Protea uses TDL across hot/wet emissions applications and also low level ambient applications.

When balancing equations for redox reactions occurring in acidic solution, it is often necessary to add H⁺ ions or the H⁺/H₂O pair to fully balance the equation. In this video, we'll walk through this process for the reaction between dichromate (Cr₂O₇²⁻) and chloride (Cl⁻) ions in acidic solution.

Project Goals Begin with FailureCommunicate, Alarm, AnnunciateTraining Beats IgnoringSelecting Detection SensorsLocation Extends Sensing LimitsInstallation and StartupHart and Other AdvancesTo confront and prevent these hazards, Greivell explains that gas detection projects should begin by answering four main questions: What does a failure look like? How do you want to communicate? What behaviors do you want? And, what's the design life? "Defining what a failure looks like begins with identifying leak scenarios, including what gas or chemical is involved, its hazard characteristics, and its vapor density, which determines where it will migrate to because heavy gases sink, while light gases flo…See more on controlglobal.comGas Detection: The Laser Approach - AWE International 16, 2019In-vehicle gas leak detection system to detect gas leaks while driving a vehicle along the buried gas pipeline network for their inspection. This type of application requires fast response time and low detection limits since the vehicle can be moving at fairly high speeds (around 40 km/hr to match normal traffic speed) and is limited in proximity to leak sources based on roadway as well as pipeline …
