  • Aerosol filtration in nanofiber filter media

    Nanofiber filter media are used in air filter applications where a compact filtration system with very high overall and fractional efficiency and low initial pressure drop  is required.  Moreover, because the aerodynamic drag force on nanofibers is very low compared to the drag on the large dust particles collected on the nanofiber media, this media is ideal for application to ...

  • A high-performance aerosol concentrator for biological agent detection

    Introduction Particle sampling from ambient air is a well-developed technology described in many texts (e.g., Vincent 1989; Willeke and Baron 1993; Hinds 1999). However, there are many cases in which the concentration of airborne particles is so low that it becomes necessary to sample for extended periods of time to collect enough mass for chemical or biological characterization of the ...

  • Application of the Steam Jet Aerosol Collector (SJAC) for differential measurements of organic compounds in the gas vs. particle phase

    A modified Steam Jet Aerosol Collector (SJAC) for semivolatile organic compounds has been investigated. Gas phase and particle phase were investigated separately. The SJAC is based on a water condensational growth sampling system. For determination of gaseous compounds an XAD adsorbent cartridge was applied after particle collection. Collection particle efficiency was examined using hydrophobic ...

  • Observation based analysis for the determination of equilibrium time constant between ammonia, acid gases, and fine particles

    Experimental measurements of ammonia, acid gases, and the inorganic components of atmospheric aerosols were made at a commercial hog farm in eastern North Carolina from May 1998 to June 1999 by an annular denuder system (ADS). The ADS consisted of a cyclone separator, one diffusion denuder coated with sodium carbonate, another diffusion denuder with citric acid, and a filter pack containing ...

  • Polyurethane Foam as an Effective Adsorbent for Pesticides in Air (GC Analysis)

    Polyurethane foam (PUF) is a lightweight, easy-to-use material for sampling pesticides in air. Low back pressure allows sampling times and representative samples. A PUF filter cartridge designed to attach to the front of an ORBO-1000 PUF sampling cartridge traps aerosols and particulate matter, is easily and conveniently assembled, and can be removed from the ORBO-1000 cartridge and capped ...

  • Can protective garments be wearable filters?

    Protective garments for medical, civilian safety and military applications range from disposable lightweight fabrics to multilayered fabrics and laminated barrier materials, depending upon the nature of the contamination that threatens the wearer. Usually, only full barrier garments, such as the Level A liquid splash protective garments provide full protection from aerosols, and this is due to ...

  • Scrubers with a level head

    The available methods for removing pollutants from a gas stream are numerous, to say the least. A popular method, scrubbers allow users to separate gases and solids by allowing the gas to come into contact with a liquid stream. In the end, the pollutants are washed away in the effluent, and the gas exits the system to be used in later processes or to be released into the atmosphere. For many ...

  • Cigarette smoke: size distribution and effects on filters

    Cigarette smoke is an important aerosol in the air filtration industry and research. It is an unwanted aerosol and therefore there are many applications for air filtration (ex. cigarette filters, residential and commercial ventilation filters, home air cleaners). Cigarette smoke is especially important to air filter performance for several reasons. First, the size of cigarette smoke particles ...

  • Maintain a Healthy Workplace with Oil Mist Collectors

    Many machining shops use a variety of metal working fluids, which support the creation of the metal components. During the creation process, lubricants and coolants get converted into vapors, aerosols and mist, which can be very harmful to workers who work in the facility. The inhalation of metal working fluids can lead to a number of medical conditions, which includes irritation of the eyes, ...

  • The IMPROVE_A Temperature Protocol for Thermal/Optical Carbon Analysis: Maintaining Consistency with a Long-Term Database

    Thermally derived carbon fractions including organic carbon (OC) and elemental carbon (EC) have been reported for the U.S. Interagency Monitoring of PROtected Visual Environments (IMPROVE) network since 1987 and have been found useful in source apportionment studies and to evaluate quartz-fiber filter adsorption of organic vapors. The IMPROVE_A temperature protocol defines temperature plateaus ...

  • Development of a Cleaning Validation Method for MICRO® A07 Citric Acid Cleaner Using HPLC-CAD

    Abstract A high performance liquid chromatography (HPLC) method with a Corona Charged Aerosol detector for the cleaning validation of MICRO* A07 Citric Acid Cleaner residue has been developed. The pooled average repeatability of 3 replicates at 6 concentration levels expressed as RSD was 1.3 % while the pooled average intermediate precision (intra-day repeatability in 3 days) of 3 replicates ...

  • Breathe easy: The importance of emission reduction and energy efficiency

    Breathe easy Blue oil mist is an unwelcome by-product of industrial work in the energy sector. contec specialises in high-powered, energy efficient and environmentally friendly oil mist filtration systems that reduce health risks and are an inexpensive alternative to traditional exhaust piping. The high concentrations of blue oil mist produced by industrial ...

  • Engine detonation with bioethanol cavitation

    Bioethanol is an alcohol of an organic origin which receives from a sugar ferment reaction. In the process of ethanol formation, starch from grains of plants turns in simple sugar in reaction with enzymes. Natural sugar ferments with yeast and form a mix of alcohol, water and unfermented remains. Alcohol is separated from a mix in distillation capacities and additionally clears in rectifying ...

  • Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

    Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...

  • Comprehensive analysis of tobacco smoke using TD–GC×GC–TOF MS with Tandem Ionisation

    The hazardous constituents of cigarette smoke have attracted considerable attention lately, especially with increasing regulation around the world limiting or banning smoking in public places – and even in private cars if children are present. From an analytical perspective, however, there is much that remains to be learnt about the composition of cigarette smoke, because of its high degree ...

  • Tackling waste in the sands of the Sahara

    When gas was discovered in the mid Sahara areas of North Africa in the 1990s Andy Ive was asked by BP to help set up the water and waste infrastructure for what amounted to four small towns 600 km into the desert. No local infrastructure at all existed for the waste and water to be produced by 2-3000 workers. IVE overcame sandstorms, extreme heat, poisonous snakes and patented a novel solution to ...
