A Comparison of Point Sensors and Open Path Monitors For Toxic Gas (esp. HF) Monitoring

Point Sensors Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is ...

Safety Systems Depend on Reliable Field Sensors (Emphasis on Fire and Gas Detectors)

Abstract Because not all hazards are the same, identifying and quantifying the hazard is the starting point in choosing sensing technology. Not all detectors are the same, and they should be selected according to their ability to detect the hazard. This paper gives a broad summary of technologies that provide users reliable responses to hazardous conditions, that minimise false ...

Detecting Hydrogen Gas and Fires: Seeing the Unseen

Hydrogen usage is growing. The general public sees and reads about hydrogen as an alternative fuel for cars. However, the big use for hydrogen is found in hydrocarbon processing and other important manufacturing processes. Hydrogen is the first element on the periodic table and is an essential element in the manufacturing of many of our everyday products. We must have respect for its explosive ...

Detection of early PFA seals (perfluoroalk-oxyethylene) degradation exposed to process gases inside a reactor chamber

Problem Statement Replacement of PFA seals inside the reactor chamber is performed according scheduled maintenance and life expectancy of the seals. Early degradation of seals goes completely undetected until there is a complete failure of the seal, letting atmospheric contaminants inside the reactor and forcing an unscheduled reactor downtime. IRGAS ...

Smart LDAR — more cost-effective?

On December 19, 2008, EPA issued a final rule establishing a voluntary Alternative Work Practice (AWP) to detect leaks of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from process equipment (FR Vol. 73, Number 246), thereby providing the regulated community additional flexibility in complying with leak detection and repair (LDAR) requirements. The AWP allows owners or ...

A comparison of two solid phase extraction methods for the analysis of Polyaromatic Hydrocarbons in butter

Background Polyaromatic hydrocarbons (PAHs) are ubiquitous in the environment, resulting from both natural and manmade sources of combustion. Farm animals, such as cows, can become exposed to them through both consumption of contaminated feed and water, and inhalation of contaminated atmosphere ...
