Detecting dangers in dairy: What gases should you be aware of?
Global demand for dairy continues to increase in large part due to population growth, rising incomes and urbanisation. Millions of farmers worldwide tend approximately 270 million dairy cows to produce milk. Throughout the dairy farm industry there are a variety of gas hazards that pose a risk to those working...
Combining Fixed & Portable Gas Detectors for Complete Solutions
Gas detectors are usually categorised as either being fixed, portable or transportable. All of these types have a range of methods of detecting gas or vapour hazards and have their own strengths and weaknesses. Selecting the correct solution depends on the circumstance of operation, topography of the site or application...
Simultaneous multi-gas detection needs only sub-μL analyte
Trace gas detection based on laser absorption spectroscopy (LAS) is a powerful technique due to its high sensitivity and selectivity, and it is widely used in many fields. Most of current works are performed using a single frequency laser targeting only one species. Study of the interaction between different components...
Researchers Present Better Ways to Detect Ethylene Gas
Background The simplest alkene, ethylene, is composed of two double-bonded carbon atoms and four hydrogen atoms. With an ambient air concentration of around 2 parts per billion (ppb), it can readily diffuse in the air. One of the main precursors for rapid ozone generation in metropolitan settings is ethylene, which is formed...
Where Do Amine Emissions Come From?
As derivatives of ammonia, amines are a group of chemical compounds that have a variety of practical applications in today’s modern world. They’re used as an ingredient in certain pharmaceuticals, as well as epoxy resin curing agents and dyes. However, one of the most common and contemporary uses of amines...
Detectors are now smarter and lighter than ever before
Safety managers should know how important it is to keep workers mobile in the field without leaving them vulnerable to hazardous gases. Workers have been using portable gas detectors for years, especially when working in confined spaces and on-site locations with questionable air quality. This allows them to move around...
Laser writing may enable ‘electronic nose’ for multi-gas detector
Environmental sensors are a step closer to simultaneously sniffing out multiple gases that could indicate disease or pollution, thanks to a Penn State research. Huanyu “Larry” Cheng, assistant professor of engineering science and mechanics in the College of Engineering, and Lauren Zarzar, assistant professor of chemistry in Eberly College of...
Advantages of Leak Detection Technology in Power Plants
The first step to solving a problem is recognizing that one is present. An operations team cannot adequately put a sufficient maintenance plan in place if there is no awareness that maintenance is required. One particular area that used to suffer much more regularly from this lack of diagnosis in a...
