Photoionisation Detector (PID) for Arson Investigation

One such tool for the detection of accelerants at fire scenes recommended by investigators3 is the photoionisation detector (PID) which has already proven to be an ideal solution for the detection of relatively low level VOCs for health & safety and environmental applications. These devices are battery powered and portable and can be deployed rapidly and safely to test areas between ...

Community Solar Garden Powers Ontario Homes & Businesses - Case Study

Overview: A new analysis from the National Renewable Energy Laboratory finds that shared photovoltaic (PV) solar systems — also called community solar gar- dens — could account for one-third to one-half of all solar PV power in the United States by 2020. These shared community solar systems greatly benefit the many business- es and homes (especially rental properties) that have been ...

Air pollution monitoring for mines: a solution for cost effective measurements

Air pollution is one of the main environmental problems to be addressed by the EU. In order to foster sustainable development and mitigate climate change, it is therefore important to provide national and regional authorities with appropriate measures to reduce criteria pollutants (PM 10, PM2.5, O3, CO2, SO2 and NOx) concentrations in air. Many cities are not able of meeting the implemented EU ...

Area Monitoring: Diffusion Sampling

Indoor and outdoor gas hazards that exist in open areas are usually monitored using diffusion-type sensors. A diffusion sensor has no active sample-drawing system; diffusion sensors rely on the ambient air movement and pressure to deliver the sample to the sensing element. Diffusion-type sensors are a reliable and cost-effective way to monitor open area gas hazards. When installing diffusion ...

A Complete Guide to Benzene

Why is Benzene so hazardous? VOCs have a significant vapour pressure at normal ambient temperature which means they evaporate (volatilise) at low temperatures so they can easily enter the body through normal breathing but can also be absorbed through the skin or by swallowing material containing it. The effects on worker’s health depends upon how much benzene they are exposed to and for ...

Patented Fence Electrode Eliminates Humidity Effects on Ion Science PIDs

Introduction In the past, a major limitation to the use of PIDs was their susceptibility to ambient humidity. Humidity effects came in two forms: 1) a decrease in response to VOCs due to a quenching effect as humidity increased (false negative) and 2) a sharp rise and drifting response when subject to very high humidities of typically >90% RH (false positive). The latter response was avoided ...

Safe Landings Whatever the Weather: Lufft Sensors on Airports

Pilots, air traffic controllers and airport operators do their best to make air travel safer and more efficient. Sometimes, however, flight security depends on external factors we can hardly influence. This especially refers to risky weather conditions: Strong winds, icy cold or strong precipitation can have serious consequences. On average, 23% of all aircraft accidents and 68% of canceled ...

Gas Monitoring for Ventilation Control and Energy Management

The growing demand for underground and enclosed parking and maintenance garages (resulting from limitations on land availability) has increased the awareness and need for proper ventilation and control systems. In addition, increased health and safety programs have only added to the concerns of toxic and combustible gases in confined or enclosed spaces. Historically, ventilation and make-up air ...
