  • Construction of a low–cost laser–based multiplexed spectrometer: a potential probe for environmental pollution monitoring

    A low–cost, sensitive, laser–based (Helium Neon; He–Ne) optical Fourier–transformed (multiplexed) spectrometer has been constructed for the quantification of suspended particulates in the air. The optomechanical features of the spectrometer are presented together with a theoretical framework of its operation. The apparatus is calibrated by using a standard commercial spectrophotometer and has ...

  • 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 ...
