  • A Comparison of Point Sensors and Open Path Monitors For Toxic Gas (esp. HF) Monitoring

    Point Sensors Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is ...

  • Online Odors Monitoring in Waste Water Treatment Plants

    Odors are very distinct air contaminants as they generate nuisances (see note at the end). The factors playing a role in the determination of odor annoyance are : odor concentration and intensity, frequency, appreciation, duration, synergy and location. Chromatotec proposes an automated solution to well identify the origin and the level of odors. Technology Description We offer a ...

  • Application in renewable energies field : odor online monitoring in methanization process

    When odor issues occur at an industrial site, rapid diagnosis must be done and a strategy defined to treat odor sources definitively. Today, the sensory panel approach using dynamic olfactometry analysis is considered as first approach to rank odor sources and subsequently to treat the most noxious odors. When investigating the source of the odor, an online monitoring system provides for the best ...

  • Every breath you take — air quality in Europe

    The characters in this story are fictional. However the data are real. The story is set on 27 July 2008 when an air quality warning was issued in Brussels. Anna is 37 years old and lives in the centre of Brussels. She and her young son Johan are planning a trip outside the busy city. Anna suffers from asthma and her doctor has warned of the dangers of air pollution, especially on hot summer days. ...

  • Determining levels of moisture permeation through Kalrez and Chemraz o-ring material

    Problem Statement As the manufacturers of corrosive resistant gas cells we are often called upon to design a system for the detection of moisture in various gases. Most of our requests are to detect moisture in the low ppb levels. This can be a rather difficult task to accomplish when the surrounding environment has high levels of moisture (humidity). There are several steps that we ...
