QROS utilises a number of analytical techniques depending on the contaminant under investigation and/or the limits of detection required. For the most part we investigate hydrocarbon and heavy metal contaminants and both these normally use fluorescence as a method of detection, either in the ultraviolet (UV) spectrum for hydrocarbons or in the X ray spectrum for heavy metals. Both these techniques have been utilised in labs for some years but have only recently been reliably available as hand held or portable instruments for field use.


Other analytical techniques employed rely on spectrophotometric determination for a range of different contaminants, anodic stripping voltammetry (ASV) for heavy metals at ppb levels and traditional potentiometric sensors probes for pH.


QROS  also develop on site analysers, either in house or in partnership with a third party.

QROS provide on-site analysis for the following contaminants. Scroll through the pop-up menus below to find out more about the techniques.


Hydrocarbons – Fuels Oils (diesel, petrol, jet fuel, heating oil etc), Heavy Oils, Insulating oils, Lubricating oils etc


Poly Aromatic Hydrocarbons - Tars, Creosotes and Combustion of Organic compounds, Petroleum derived compounds. Sum of the target 16 PAHs, total C10 - C35 aromatics and Benzo-a-Pyrene


Heavy Metals – Lead (Pb), Zinc (Zn), Copper (Cu), Arsenic (As), Mercury (Hg), Cadmium (Cd), Nickel (Ni), Chromium (Cr), Selenium (Se) etc


Ammonia, Chloride, Cyanide, Sulphate, Phenols, Nitrate


Chlorinated Solvents


Acidity (pH)


PCB (Polychlorinated Biphenyl)


QROS can also adapt or develop methods for other contaminants.
