Understanding the business impact of chemical contamination on food products requires a rapid response.

RSSL is your expert partner for resolving contamination issues, from initial identification of the contaminants in foods to recognising its root cause (whether accidental or malicious), and taking appropriate corrective action.

We have 30 years’ experience in chemical contamination identification, including unknown peak identification, taint and off-flavour investigation and suspected contamination events.

Whatever the contaminant, our expertise in sampling, extraction and analytical methods, allows us to provide you with thorough and effective analysis.

We can identify:-

Our chemical contamination analytical services include:-

  • Chromatographic analysis
  • Spectroscopic analysis
  • Elemental determination (RSSL testing capabilities have been extended with the introduction of an elemental analyser, allowing for the testing of carbon, hydrogen, sulphur, nitrogen and oxygen)
  • Energy dispersive x-ray analysis in the Scanning Electron Microscope
  • Semi-quantitative metals screen for ~70 elements
