Toxicity of pure chemicals is assessed using respirometers by adding increasing concentrations to an active culture. The concentration at which oxygen uptake or gas production begins to decrease is known as the “threshold toxicant concentration.”
A safe laboratory environment requires an
effective method for clearing toxic material from fume hoods. Since all handling of toxic
materials is completed in these hoods, it is
critical to have a procedure to evaluate their
operation to assure adequate protection for
laboratory workers. The InfraRan Specific
Vapor Analyzer, factory calibrated for SF6, is an ideal instrument for measuring fume hood
efficiency in accordance with ASHRAE and
other standards. Manufacturers identify the flow
dynamics (factors that...
Motor vehicle emissions are a major source of air pollution in urban areas and impact the lives of billions of people every day around the world. Motor vehicle exhaust contains toxic chemicals that are harmful to people’s health when exposed at certain levels. These toxic fumes cause smog in the atmosphere, which can affect very broad regional air sheds and contribute to the formation of cancer. Teledyne API has several products specifically designed to meet the challenging demands of near-roadside air...
Compressed breathing air is subject to strict limits of harmful contaminants defined in European standard EN 12021 and various defence standards such as DEF STAN 68-284 issue 3. The testing interval of breathing air compressors and associated equipment is 3 months and gases tested include carbon monoxide, carbon dioxide and oil vapour defined as hexane and heavier hydrocarbons. EN 12021 covers underwater applications including self-contained open circuit compressed gas breathing (SCUBA) and compressed gas line...
CairNet is a simple and efficient way to monitor processes and plant surroundings via a wireless communicating network and autonomous (solar panel and battery). CairNet surveys fugitive emissions of toxic gases or odourous gases around waste water treatment plants (WWTP), allowing you to react quickly to gas leaks. CairNet allows the wireless survey of hundreds of measurement points within a 200m radius of the wireless receiver for a much efficient installation cost.
Cairpol systems can be used for fugitive...
