Environmental analysis

In line with the new proposed EU council amendment to Directive 98/83/EC Annex I and III, which now includes 20 PFAS compounds and sets a Sum of PFASs limit of 0.1ug/l, this reflects the World Health Organisation’s recommendations.

Using LC-MS/MS RPS can detect sub nanogram levels of these PFAS compound in surface water, groundwater and treated effluents.

PFECHS - a PFAS Compound of emerging interest

RPS can also provide the analysis of Perfluoroethylcyclohexane Sulfonate (PFECHS) which has been utilised extensively as a hydraulic fluid additive inhibit corrosion especially in aircraft systems and has recently been identified as a likely source of this product in surface waters, fish and sediments in the proximity to airport facilities.

As PFECHS is a technical mixture it contains over 13 constituents in varying ratios which can be determined by LC-MS/MS.
