Measuring equipment must be checked regularly, if the quality of the measurement results has changed during every-day use. The user should perform these checks at fixed time intervals. Balances and Scales are tested with an external weight piece. This test weight must have a valid calibration certificate issued by an accredited calibration lab. The tests should be performed in fixed, regular intervals and the results should be documented in a traceable way.
Making smoke in a very open environment or external environment can be a challenging! An oil-based smoke generator, such as a ViCount system, can produce dramatically more artificial smoke than multiple water based systems. This is due to the fact that the smoke ViCounts produce, being oil-based, does not evaporate in the same way and speed that water-based smoke does. The smoke from a ViCount smoke generator will travel for 1000`s of meters, compared to a typical water based smoke machine that may produce a...

Closed chamber gas flux measurements can be made with Protea FTIR analysers to allow researchers in the field of atmospheric gas analysis from agricultural and livestock to measure evolved gases such as N2O, CO2, CO, NH3, and CH4. Nitrous oxide (N2O) and Methane (CH4) emissions from soil, plant and livestock are especially important gases to measure, given their high potential as greenhouse gases (GHGs). NH3, whilst not a greenhouse gas on the scale of N2O, CH4 and CO2, is a major emission from agricultural, such...
The act of capturing and storing CO2 produced from large scale combustion plants such as power stations is becoming more and more favourable and feasible. One of the most common post-combustion CO2 capture methods is by absorption. The absorption plant can be added on to the existing combustion process, with the flue gas first passing through an absorption column where the CO2 reacts with an absorber. Amines of different types are used as the absorber. An amine CO2 capture plant can capture as much as 90% of the...
It has been established that organic aerosol (OA) makes up for a major fraction of fine particulate matter in all region of the atmosphere. This fraction accounts approximately for half of the total PM2.5 dry mass.1,2 Primary OA is directly emitted in the troposphere from anthropological and natural sources whereas secondary OA (SOA) is formed in-situ in the atmosphere from the oxidation of biogenic or anthropogenic gas-phase precursors and subsequent partitioning of the less volatile products into the particle...
The chemistry underpinning electrolysed water (EW) has been known for centuries, in fact demonstrations were performed in the first decade of the 19th century at the Royal Society by Nicholson, Carlise and Davy. The first large scale application of electrochemical disinfection occurred a century later when the technology was used on a large scale for disinfecting drinking water. Electrolysed Water is produced by inducing an over-potential in a saline solution. This is similar in principle to the storage of...
The aluminium industry is the major source of perflurocarbon (PFC) emissions to the atmosphere, which are a major contributor to global warming. PFCs have greenhouse gas effects up to 10000 times that of CO2. Emissions have been reduced over the last 20 years, but further reductions are harder to achieve as all the mechanisms for PFC production are not known. In order to better understand the production of PFC on an industrial level, laboratory studies have been carried out using a small scale cell.
A number of treatment products are often added to prevent corrosion, scaling and fouling. Coating of sensors and other effects of these products must be taken into account when selecting analyzers. Discharge monitoring needs special attention because zero measurements must be reliable over time with little maintenance.
Once an archetypal example of manual production, the winery and brewery industries now incorporate sophisticated processes to ensure high quality levels and efficient output. In some cases traditional approaches have simply been scaled up or put under more stringent monitoring, whilst in others innovations such as nitrogen-pressurised canning have been introduced. However, whichever approach has been followed there is also a growing realisation of the gas hazards that are associated with both new and old processes,...
A general understanding of the separate and combined effects of several weather elements on fire behavior is needed to plan and execute a good prescribed burn. Because weather and fuel factors interact, an experienced prescribed burner can conduct a successful burn even with one or more factors slightly outside the desired range—as long as they are offset by other factors. Accurate fire weather monitoring of fire danger indices via the RAWS network, providing historical data leading up to a prescribed burn is...
