Chemical analyses and hazardous substances

We work in the following areas:
  • health safety of light industry products
  • hazardous substances in construction products (hygiene, health and environmental protection)
  • hygienic requirements for products coming into direct contact with food and drinking water
  • water and sludge analysis
  • waste analysis, leaching tests
  • hazardous substances in packaging materials
  • ecotoxicity
  • fire technical properties of flammable liquids
  • analysis according to the customer's wishes
In addition to common laboratory procedures, we use the following instrumental methods:
  • atomic absorption spectrometry (AAS)
  • spectrophotometry (UV-VIS)
  • liquid chromatography (HPLC)
  • gas mass spectrometry (GC-MS)
