ROUND-ROBIN STUDY OF THE INA-3 USERS FORUM - TECHNICAL AL AND STEEL SAMPLES

Parallel to the introduction of the first commercial electron-gas SNMS system INA-3, a forum of nearly all middle-European users was establi shed. One of the first activities was a round robin study to check the reproducibility of quantification parameters. First results showed pr onounced differences of sensitivity factors in many cases. As a conseq uence some experimental rules have been worked out. Their effect on re producibility was checked in a second round robin study.
