Trace Organics Analysis

Using state of the art instrumentation such as LC-MS/MS and GC-MS/MS, RPS can offer ultra low level LODs to suit your requirements; however core expertise remains the analysis of trace levels of organic contaminants, for example pesticides and herbicides, in water, food and beverage, feeds, soil, sewage and sludge. Recently added techniques include Explosive and Chemical Weapon Residue Analysis.

Our areas of analytical expertise include:

Polybrominated Dyphenyl Ethers

Bisphenol A


Organotin compounds

Pesticides, Herbicides, Fungicides, Insecticides and Rodenticides

Acid Herbicides

Carbamates and N-methyl carbamate insecticides

Glyphosate & AMPA

Crop specific suites (e.g. potatoes, wheat)

Organochlorine (OCL) pesticide suites

Organophosphorous (OP) pesticide suites

Triazine herbicide suites

Urea herbicides and sulfonylurea herdicide suites


PAH suites (including EPA 16 and WHO 6)

PCB Suites CEN 25 (including ICES 7, and WHO 12)

Phenols (alkyl phenols and chlorinated phenols)

PAH derivatives



Alcohol & solvent suites

Licensed Drugs

Phthalates & other plasticisers

Acrylates and methacrylates

Anionic, cationic and non-ionic detergents

Case Studies



RPS was commissioned to conduct a marine Environmental Impact Assessment (EIA) including the associated chemical analysis from the site of the wrecked oil tanker, the RFA Darkdale, that was sunk in the South Atlantic during the Second World War.

The wreck site contained approximately 3,000 tons of fuel oil and 850 tons of aviation fuel. After a large oil leak in 2010, further understanding was needed of the condition of the wreck and the extent of the oil leak.

RPS carried out a desktop baseline study which provided background information of the problem, together with a field survey of the site and surrounding areas. This field survey involved the collection of information about the wreck site conditions and samples were obtained for analysis at RPS’ laboratory in Hertfordshire.

RPS carried out hydrocarbon content analysis on water, sediment, benthic ecology and fish samples The results of these analyses were used to conduct an eco-toxicological assessment, benthic fauna analysis and socio-economic study. The analytical data was further used to complete a computational oil spill model to evaluate the potential risk posed by the remaining oil.
