Information for 2020

  • Interlaboratory comparisons with natural samples (ground, surface, waste or drinking water, partly spiked) will be on offer covering all parameters, except BTEX. This service is made possible by the cooperation between IFA-Tulln and the, Umweltbundesamt GmbH's (UBA)accredited testing laboratory for environmental, GMO & fuel analysis. Samples for BTEX in real water samples will be performed in 2021.
  • 2020 our partner institute, the UBA, organises again an interlaboratory comparison test for pesticides in accordance with the drinking water ordinance (PM03).
  • In order to facilitate calculation of the target values with statistical relevance for interlaboratory comparisons with natural water, a minimum number of 15 participants is necessary. Otherwise, we reserve the right to refuse the realisation of the concerning round.
  • In round N150 (major ions) the Umweltbundesamt GmbH will provide Ntot and pH as additional parameters.
  • In round N151 (major ions) the IFA Tulln will provide silicon and fluoride as additional parameters.
  • In round N152 and N154 (major ions) the IFA Tulln will provide KMnO4-Index as an additional parameter.
  • In round N153 (major ions) the IFA Tulln will provide easily liberatable cyanide as an additional parameter.
  • In round M152 (metals and trace elements) antimony, barium, cerium, cobalt, lithium, molybdenum, silver, tin and vanadium will be included.
  • In round CB07 the IFA Tulln offers the combination of the parameter groups VHH and BTEX&MTBE in the same interlaboratory comparison. The extent of participation is selectable (VHH, BTEX&MTBE or both). Evaluation of the round will be carried out in a joint report.
  • In round SP05 (sum parameters) the Umweltbundesamt GmbH offers the combination of hydrocarbon oil index and phenol index.
    It is also possible to select only the hydrocarbon oil index, selection of phenol index only is not possible. Evaluation of the round will be carried out in a joint report.
