All four samples (two spruce, one ash and one pine samples) were prepared from BFW/Austria, many thanks to Walter Wuggenig/Austria and his employees for collecting two samples.
For each parameter (total element concentration) four replicates are necessary for this Interlaboratory Test. The results for the elements S, N. P, K, Ca, Mg, C, Zn, Mn, Fe, Cu, Pb, Cd and B will be evaluated. Mandatory parameters are S, N, P, K, Ca, Mg and C! Other additional elements can be analysed, but only the results will be given in the report, without detailed statistical evaluation. An overview of the elements that can be analysed and the proper units for all elements are avalable here. Don't forget to use only recommended methods which are described in the ICP-Forests submanual Sampling and Analysis of Needles and Leaves. The recommanded minimum sample weight is 250 mg. All results must be calculated on dry weight (105°C).
Data submission and confirmation of the results must be
done by the participating laboratories on their own over the internet
with a web-based interface to an Oracle database.
If your laboratory is analysing foliar/litterfall samples for the ICP-Forests Programme
on Level II, the interlaboratory test samples should be analysed within this
sample batch, but they must be finished before the deadline.
Some words about the costs - all participants had to pay a participation fee of 190 Euros. You will get the debit note with the test samples and the payment of the participation fee must be done before data submission (Data submission page will be opened after we received your participation fee!). Please, indicate the debit number and the laboratory-code number on the transfer order! If somebody really has problems to pay this fee - please, contact me - I will try to find a solution for this laboratory.
Don't forget - if there are changes in responsible person, name, address, phone number and the e-mail address - to correct this information in the database (see Addresses of the labs). For further information about the current ringtest it is important for me to have your correct address.
New participants should send me an e-mail, they will be informed in time about the next Foliar Interlaboratory Comparison Test.
