Information for 2018
Interlaboratory comparisons with natural samples (ground and/or surface water,
partly spiked) will be on offer covering all parameters. This service is made possible
by the cooperation between IFA-Tulln and the Umweltbundesamt GmbH's accredited testing
laboratory for environmental, GMO & fuel analysis.
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 N140 (major ions) the Umweltbundesamt GmbH will provide Ntot and pH as additional parameters.
In round N141 (major ions) we will provide silicon and fluoride as additional parameters.
In round N142 and N144 (major ions) we will provide KMnO4-Index as an additional parameter.
In round N143 (major ions) we will provide cyanide as an additional parameter.
In round M142 (metals and trace elements) antimony, barium, cerium,
cobalt, lithium, molybdenum, silver, tin and vanadium will be included.
In round CB05 we offer the combination of the parameter groups VOC and
BTEX&MTBE in the same interlaboratory comparison. The extent of participation is
selectable (VOC, BTEX&MTBE or both). Evaluation of the round will be carried out in a joint report.
New: In SP03 (sum parameters) we offer the combination of hydrocarbon oil index and phenol index.
It is also possible to select only the hydrocarbon oil index. Evaluation of the round will be carried out in a joint report.
New: Round AZ5 (Pharmaceuticals, Industrial Chemicals and Artificial Sweeteners) has been enlarged with the parameters 4-Acetylaminoantipyrine, Amidotrizoic acid,
Atenolol, Bisoprolol, 10,11-Dihydro-10,11-Dihydroxycarbamazepine, 4-Formylaminoantipyrine and Iopamidol.
z-Score-criteria will be recalculated on the basis of all IFA-Test Systems interlaboratory
comparisons organised between 2007 and 2017 by the end of the year.
