General information

  • The sample types/matrices are chosen to represent the materials which you normally analyse.
  • The samples types are plant materials, woods and waste (sewage sludge).
  • The samples are dried, milled and sieved to <0.5 mm and are stable for over a number of years when stored at room temperature.
  • The homogeneity of each batch of samples is tested on a selection of parameters.
  • You analyze the test materials according to your normal validated methods and procedures for those elements and parameters you are interested in.
  • Your results are processed at WEPAL/QUASIMEME and published every three months under confidential code names.
  • The reports contain all data, statistical evaluation including Z-score plots and method information about the method used.
  • Your reports are available within one month after the submission deadline.
  • New determinands can be added on request.
