    Laboratory Weighing - Filter Weighing

    Traffic means mobility and air emissions. Thanks to economical advantages, diesel engine becomes more and more popular, but particle emission is strictly restricted by regulations. Determining the weight of particulate matter (PM) is a key task in the automotive industry and one which is likely to become even more important as emissions standards become stricter. To allow fast and easy measurement of particulate matter at any time, METTLER TOLEDO has developed new filter weighing solutions.

    Waste water treatment plants Personnel Safety & H2S filter management

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. As a result of the confinement of the waste water stations, toxic components such as H2S...

  • Dust monitoring and Sand Storm Monitoring

    The frequency and intensity of dust and sand storms in many parts of the world are steadily increasing due to droughts and climate change. The severity of such storms is anticipated to increase over the coming years. These dust storms may last hours or days and cause huge damage and imposed a heavy toll on society with its physical effects, such as visibility reduction, heavy winds, red sky, hailstone and severe lightning. Such Dust storms, have a negative impact on human health, and industrial products and...

    Monitoring solutions for the dust collectors

    Most industrial processes have dust collectors of some form or other, the most popular being filter bag houses. Very few of these are covered by regulation other than to have a broken bag detector to prevent nuisance dusts escaping and creating a local nuisance. The CODEL StakGard is a low cost

    Air quality monitoring

    To estimate the effects of aerosols on health and climate, it is essential to know their chemical composition. Sampling is done using two different types of aerosol collector. The first type are filter collectors that are based on the deposition of suspended particles on surfaces; the second type are powerful aerosol collectors.

    Air monitoring for laboratories

    Many of the air quality analyses can be performed with standard laboratory consumables, such as traditional filter papers. However, some analyses require materials with specific features, for example filters with low metal levels.

    Common air monitoring applications include:

    • Air quality testing of ambient environment and emissions. Includes particulate monitoring methods such as PM2.5 and PM10, and chemical analysis such as heavy metals determination.
    • Asbestos sampling and analysis

  • Drinking water solutions for the nitrate monitoring

    Problem: Nitrate, the most stable form of nitrogen in water, is found in both ground and surface water and originates from both natural and anthropogenic sources. Due to its high solubility in water, nitrate is not filtered out from groundwater like other contaminants. Removing nitrates from source water is important as elevated levels in drinking water can cause serious health effects when ingested.

    TPH in Soil Remediation

    InfraCal TOG/TPH Analyzers allow for TPH (Total Petroleum Hydrocarbons) in soil testing at remediation sites such as leaking underground storage tanks and produced water evaporation ponds. Site managers can avoid having costly soil remediation equipment sit idle while waiting for off-site lab results. Sampling requires a few simple steps that can be performed by non-technical personnel. The soil is mixed with the extraction solvent, shaken, filtered, and then presented to the InfraCal Analyzer for measurement....

  • Particulates PM10 PM2.5 TSP monitoring

    Sampling dust and particulate matter is important as dust and particulate matter can affect the health of human populations, as well as the natural environment. Dust and particulate matter can cause respiratory problems when breathed in by humans. Dust and particulates above 10 micrometer (PM10) are filtered and generally do not enter the lungs.

  • NH3 Monitoring in Air

    NH3 (Ammonia) is a colorless gas with a distinctive pungent smell. Ammonia monitoring is essential in coal-fired power plants, where NH3 is used to reduce NOx emissions. The ammonia consumes all of the NOx, but its high concentration that is needed for these purposes also starts reacting with other things and in the process can clog up filters and cause premature failure of expensive SCR equipment and pre-heaters. Not to mention that these high levels create an irreparable damage to the environment.
