  • Office Printers Emit Ultra fine particle pollution

    We’ve heard quite a bit about particulate matter PM10s and PM2.5s as components of air pollution that we are exposed to on a daily basis. Recent research papers are highlighting the dangers of ultra fine particles (UFPs), which have a diameter of less than 0.1 micrometres (or 100 nanometres). By contrast, the diameters of particulate pollution from PM10s and ...

  • Oxygen Monitor for FOUPs in Semiconductors and Cleanrooms

    Over time, the contamination control requirements in the semiconductor industry have become more stringent. Employees now must spend more time adhering to cleaning protocols to preserve the sanitary nature of the environment and comply with regulations. The front-end unified pod (or FOUP) began appearing in semiconductors in the 1990s, serving as a transportation box to safely and ...

  • Media expansion monitoring improves filtration

    In municipal surface water treatment plants, optimum filter performance is a crucial component. Filtration is the primary treatment process at water treatment plants, and backwashing is the primary means to keep filters functioning properly to produce safe drinking water for the public. Since 2000, Entech Design, Inc. has used underwater acoustic sensing technology to monitor filter media ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Air Separation Plants and the Use of Oxygen Monitors

    Air separation plants are critical for many different industries, from clean energy to manufacturing. Nowadays, cryogenic is the most common type of distillation used to separate air into its component gases - nitrogen, oxygen, and inert gases including helium and argon. If your industry relies on air separation for product development or manufacturing, then knowing how the process works is ...

  • OSU Researchers Deploy Stevens Equipment in Study of Green Infrastructure Treatment for Groundwater Runoff

    Stormwater runoff pollution is a serious issue that faces almost every urban and suburban environment. In older city infrastructure, runoff from roofs, parking lots, and streets flows directly into the sewer system and must be handled by the municipal wastewater treatment facility, increasing the amount of work the system must undertake. For the past 30 years, the infrastructure for stormwater ...

  • Work Safely in Dusty Environments

    Dust is a term used to describe all airborne particles – these can be wood, stone, flour, concrete, grain, mould or asbestos particles as well as fumes and chemicals. Many activities create dust. Larger dust particles get lodged in the nose and throat while the smaller more dangerous particles get lodged deep in the lungs – these dust particles are the ones that can cause fatal ...

  • Selecting an Air Sampler for Bioaerosol Collection

    Indoor Air Quality (IAQ) investigators should select cost effective, efficient and the highest quality samplingequipment for evaluation of indoor environments. Particle impaction onto an adhesive surface (non-viable) or into culture media (viable) are the most widely used techniques to evaluate the presence and levels of airborne bioaerosols, particularly in non-industrial indoor environments. ...

  • Case study - Safety, Protection against corrosion and cabinet pressurisation in refineries

    The environment in a refinery is highly corrosive. This makes it necessary to deploy control systems not only to protect staff but also to protect the equipment controlling the processes, in order to ensure their reliability. Bioconservacion has equipment that is specially designed for the safety of staff, and for protecting against corrosion in control rooms and cabinet pressurisation equipment. ...

  • Biodiesel versus diesel: a pilot study comparing exhaust exposures for employees at a rural municipal facility

    Many organizations interested in renewable, domestic energy have switched from petroleum diesel to biodiesel blends for use in transportation and heavy-duty equipment. Although considerable evidence exists on the negative health effects of petroleum diesel exhaust exposures in occupational settings, there has been little research examining biodiesel exposures. Working collaboratively with a local ...

  • Black Carbon – the elephant in the room!

    Traditionally, ambient particulates have been measured gravimetrically according to their size. However, in this article Jim Mills, Managing Director of Air Monitors, will demonstrate that the time has come to change or at least augment the way ambient particulates are monitored and regulated. Air Monitors has supplied most of the UK's ambient monitoring network, but Jim will explain why the ...

  • Techniques for Soot in Oil Analysis

    Since no engine is 100% efficient, products other than carbon dioxide and water will be formed during combustion. One such product produced from incomplete combustion is soot. Soot is a mass of mainly carbon particles that are typically spherical in shape. As soot levels rise, the soot particles begin to clump together and ...

  • Application notes - viscosity measurement

    Most laboratory viscometers employ the well-known principle of rotational viscometers to measure viscosity by sensing the torque required to rotate a spindle at a constant speed while it is immersed in the sample fluid. This is because the torque, generally measured using the reaction torque on the motor, is proportional to the viscous drag on the immersed spindle and thus the viscosity of the ...

  • FTIR gas analyzers support management of fire at UK waste facility

    The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents.  Arrangements have been made in England to bring together experts from the Environment ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Solo flight tracks global Black Carbon

    On 8th January 2012 a tiny ultra-light aircraft left Ljubljana in Slovenia on a mission to circumvent the globe using the smallest amount of fuel per distance flown whilst recording ambient levels of Black Carbon (BC) – one of the most important measures of air quality in terms of both human health and climate change. UK based particulate monitoring specialist Jim Mills from Air Monitors ...
