Air Quality Monitoring
|
The Air Quality Index (AQI) is a rating scale for outdoor air based on air pollutants which affect environment and human health. Air pollutants can be in the form of gases, liquid droplets and solid particles. Several major pollutants are ozone, fine particulate matter, nitrogen dioxide, carbon monoxide and sulfur dioxide. The lower the AQI, the better is the air quality. Felix Technology provides air quality monitoring instruments to help better understanding of air quality. The focus of Felix technology is on the instruments reliability, ease of use, minimum maintenance and low cost.
The eight key air pollutants which can be measured by air quality monitoring instruments provided by Felix technology are:

As scientific researches show, there is a strong association between particulate emissions in the air and human health conditions. In addition, in order to meet industry’s regulations requirements like ISO 14698 or ISO 14644, environmental effects of the products should be considered. Felix Technology provides a wide variety of instruments which can be used for air particulate monitoring and dust monitoring.

NO/NO2/NOX Analyzer uses Chemiluminescence which is the best practical analytical method for NOx detection. When an NO (nitric oxide) molecule reacts with ozone, it is oxidized to NO2, in an excited state. A small fraction of the molecules in this excited state decays by emitting a photon (i.e. giving off light) in the near infrared portion of the spectrum. The concentration of NOx in the sample is determined by the amount of light emitted from the mixed gas sample. This technique provides an extraordinarily sensitive, selective, and linear measurement of NOx. |

CO Analyzer measures carbon monoxide by passing infrared light through sample and determining the absorbed energy and then compare this to that absorbed by a reference gas. This is accomplished with a Gas Filter wheel which alternately allows a high energy light source to pass through a CO filled chamber and a chamber with no CO present.

The Ozone Analyzer is a microprocessor-controlled analyzer for measuring low ranges of ozone in ambient air. An Ultraviolet light is passed through a sample cell. The light is absorbed, depending on the amount of ozone present. The true value of the ozone is proportional to the absorption. |

Chemiluminescent NH3 Analyzer measures ambient ammonia in selectable ranges from 0-50 ppb to 0-2,000 ppb using the chemiluminescence principle and an API designed external ammonia converter and sampling system Ranges are user selectable in 1 ppb increments and auto ranging is available. Ammonia is difficult to measure accurately because of a tendency to be absorbed into other materials. |

TRS provide a dependable, accurate and convenient method of measuring hydrogen sulfide or Total Reduced Sulfur (TRS) in levels commonly required for Ambient Air monitoring, offering ranges from 0-50 ppb to 0-10 ppm. Both analyzers convert sulfur gases to sulfur dioxide and measure concentrations using fluorescence technology. |

The H2S analyzer provides a dependable, accurate and convenient method of measuring hydrogen sulfide in levels commonly required for Ambient Air monitoring, offering ranges from 0-50 ppb to 0-10 ppm. The analyzers convert sulfur gases to sulfur dioxide and measure concentrations using fluorescence technology.
