The Advanced Sensors ATOM (Advanced Total Oil Measurement) Analyser combines numerous technologies to deliver online measurement capabilities that were previously impossible.

Features and Benefits

1.    The analyser uses a membrane inlet mass spectrometer (MIMS) to extract the components from its surrounding atmosphere (Oil, Gas or Air) to provide measurement concentrations of individual Hydrocarbons and Volatile Organic Compounds. Whilst the analyser will provided a total oil in water measurement (TOG), it will also provide measurement of the individual components such as , Benzene Toluene, Ethel Benzene, Xylene, Naphthalene, H2S, Pentane, Ethane, Ethene, Methanol, Propane, Propene etc. The Mass spec will provide these measurements approximately every 5 to 10 Minutes at least or at user configured time intervals, as required.
2.    The analyser utilises the detailed measurement information provided by the Mass Spec to calibrate the integral optical measurement device (Fluorescent or Infrared), which in turn provides a relative measurement of all the components every second.
3.    The analyser utilises Ultrasonics to ensure the membrane and optical windows remains clean.
These combined technologies deliver an analyser that provides reliable measurement of Volatile Organic Compounds (VOC’s) and Discrete hydrocarbons every second, without the need for sample preparation, cleaning/sterilisation, or expert instrumentation knowledge.
As with all Advanced Sensors products, the ATOM has been designed for simple installation and operation, with remote access, data logging, and a self-intuitive user interface.
Fluorescent, Infrared, Sonic, and Microscopy analyser techniques measure the affect on a secondary phenomena to measure hydrocarbon concentration, e.g. the absorption of light by Hydrocarbons (IR), the fluorescent levels of light from hydrocarbons, the absorption of acoustic energy (sonic) by Hydrocarbons, or the shape of visible object to identify Hydrocarbons (Microscopy). The above techniques are all credible techniques, but lack the ability or granularity to measure the individual discrete hydrocarbons present; these analyser techniques provide a macro/relative measurement. Their calibration and in turn their measurement accuracy can be rendered useless if the relative concentration any of the discrete hydrocarbons change.
Unlike the above techniques, the ATOM analyser  (MIMS) measures the levels of the discrete Hydrocarbons present, it reports these individual measurements and a total of the components selected for total concentration measurement. Should any of the discrete components change in concentration, the specific changes are measured individually and their contribution to the total user selected concentration is reported. For example, the ATOM can be configured to alarm on BTEX concentration only.
