This market is driven by law and legislations made in Europe and/or USA (US EPA). It deals with ambient air monitoring : analysis / calibration / automatic zero air in continuous 7 days a week. Ambient air monitoring: in France this service is controlled by associations that calculate the ATMO index. CHROMATOTEC instruments such as the BTX ,the Sulfur and the VOC analyzers can be a good complement of their analyzers such as O3, CO2, DUST… in the analysis of ambient air.
Nitrogen oxide (NOx) is one of the main sources of air pollution, not only it has significant influence on global warming, but also involved in the destruction of the ozone layer. Technical measures to control NOx emissions can be divided into two categories: one is so-called source control, the characteristic is by a variety of technical means, to control NOx generation in the process of combustion reaction (i.e., low NOx combustion technology). Another kind is the so-called tail control, the characteristic is...
Real-Time measurements of VOCs causing smells or adverse health effects. Monitoring of chemical contamination related to the Sick Building Syndrome. Sensory impact on passengers in aircraft cabins, cars (VIAQ) and workers in offices or family homes.
To measure the air quality in a city is a challenge. A large number of gaseous components need to be measured with high accuracy. The monitoring site needs to be representative for the city and the system has to be easy to maintain and calibrate. The OPSIS open-path monitoring systems provide a flexible solution, giving the average concentration for an area. A single OPSIS system can measure all relevant gaseous components set by the authorities, such as NO, NO2, SO2, O3, BTX, NH3.
Laundry capacity can be increased three times, using the same amount of fresh water, by recycling the wash and rinse water. Reclaimed wash and rinse water saves the cost of purchasing water, soap, heat and sewer. Reclaim your water for $1.70 per thousand gallons.
Geostatistics is vital for environmental issues as it provides the accurate and reliable solutions for mapping and uncertainty quantification needed by a sector where health is at stake and the remediation costs are considerable.
Where the pyrheliometer is most suitable to quantify the total DNI of the solar spectrum. The spectroradiometer gives details about the energy distribution which is important for PV or CPV cell research. The solar spectrum wil change with the angle of incidence and its path through the atmosphere. Photons wil be reflected, scattered or absorbed. Big absorbers of infrared irradiance are water vapor, carbon dioxide, and ozon.
Zysense manufactures the Nitric Oxide Analyzer (NOA 280i) for Nitric oxide research and analysis. In biological systems, nitric oxide is produced from the enzymatic oxidation of arginine. Three isoforms of the enzyme nitric oxide synthase (NOS) have been identified in many cell types: endothelial NOS, neuronal NOS, and inducible NOS. The biological functions of NO include action as a vasodilator, neurotransmitter, cytotoxic agent, inhibit of platelet aggregation, and activator of smooth muscle proliferation.

Environics® Ambient Monitor Calibrator with Ozone Generators facilitate dynamic calibration of ambient air analyzers. These instruments automatically perform zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, O3, hydrocarbons and other gases of interest. All ozone generators are factory calibrated using a NIST traceable ozone standard. The Series 6100, Series 6103 and Series 9100 all meet or exceed U.S. Environmental Protection Agency requirements.
Ambient air pollution is a continuous problematic since many years, and the various organizations in charge of air quality monitoring work constantly on how to improve their structures and gain the most accurate and reliable data possible. Indeed, the changes in mentality and therefore in urbanism development for example, implies an access to the data faster and at multi-location level.
Air quality monitoring reference stations used nowadays measure with an extreme accuracy in located areas, but requires a lot of...
Hydrocarbons are a family of organic chemicals consisting of carbon and hydrogen atoms arranged in a variety of ways. Hydrocarbons are found naturally in crude oil and are released into the environment with its combustion (power plants, home heaters etc).
Ozone found in ambient air can have a direct affect on human health and also has the potential to create photochemical smog. It is for this reason that the U.S. EPA has set a one hour limit of 120 ppb and an 8 hour limit of 80 ppb. Ozone has been found to affect human health by harming the respiratory and immune system. People with pre-existing respiratory damage or diseases are more likely to suffer from the affects of ozone.
The monitoring of “Ultra Pure Water” or “High Purity Water” requires the lowest possible detection limits for process analyzers. Resistivity is often around 18 MΩ. Dedicated instruments can detect infinitely small amounts (ppt e.g. parts per trillion) of ions.
