An integral part of this PT 26/1 protocol are methodical instructions with possible participant´s comments and tabulated results. The results will be processed under a code number only so the participant´s identity may not be disclosed.
The protocol PT 26/1 and PT programme (including time schedule) is also available online for download at this link:
Please send the filled-out form as an attachment to our e-mail: .
The preferable format is a PDF of the scanned file, resolution 250 DPI or more, which is optimal for our further OCR processing.
You can also send us the protocol in any MS Word format and along with it the confirmed scan of the first page (in the same e-mail as the best).
It is not necessary for our purposes to receive the originals in print by mail, the electronic version suffices. We also hope to save you effort and expenses in this way.
Methodical instructions for PT 26/1 participants
Prior to analysis of a PT 26/1 sample please the calibration should be validated by the regular procedure as per the laboratory Q. A. instructions.
Please identify a main or prevailing RM used for the calibration:
List the elements, for which a correction was applied:
Instruction to the analysis
Fill the results of five paralel determinations in the tables of the protocol*. The number of digits should comply with that in the approximate values indicated in the top of tables.
*If more than one technique is applied (AES and RFS, AES and wet-way analysis), please give the particular sets of results in separed copies of the protocol. Each participant will be assigned his code number for each method applied. The same principle may be used for stable and mobile instrument.
