Hi tf123456
The problem with that file is that some masses are repeated (e.g. Sr88). iolite cannot process the data because if you ask iolite to, for example, use Sr88 in a ratio, it won't know which channel you mean.
We'll improve the importer to let you know that this is the case, but perhaps you can adjust the output from the iCap so that duplicate channels are not in the exported file?
Kind regards,
Bence
