PetroChek enables in-situ, real-time, monitoring of crude and refined hydrocarbons within both fresh and marine water systems. The monitor detects fluorescent poly aromatic hydrocarbons (PAHs) that are inherent in crude oil and refined fuels and lubricants.

Accidental or deliberate spillage of crude or refined hydrocarbons can have catastrophic consequences to freshwater and marine environments. Impacts to fauna and flora can be devastating and in freshwater environments it can lead to significant damage and costs to drinking water treatment plants. In cases where there is historical contamination, PetroChek can be effectively used as a portable or online monitor to identify and quantify the problem or help control the remediation process. Typical treatment technologies include aeration and activated carbon and big savings can be made through effective monitoring and control.

The system can combine a sensor with a depth rating of 600m with either a wireless roamer/battery that can connect to a tablet/PDA or laptop connectivity. It provides a low cost high performance sensor for marine, freshwater or process applications. PetroChek can easily be adapted to operate inline/online with a specially designed flow cell and pumps requiring very little maintenance or calibration.

Fluorescence is the emission of light by a substance that has absorbed light. In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed light. Fluorometry is the measurement of this fluorescence. Different molecules absorb and emit light at specific wavelengths. In order to effectively use Fluorometry as a tool for environmental analysis the specific wavelengths of the absorbed and emitted light for the target molecules/compounds needs to be known. Modern Water fluorometers use LED light source to excite the molecules and then measure the emittance at the desired wavelength. The intensity of the emitted light provides the concentration of the target compound.
