Thank you for your advice. However all the analyses were done at two different
'dedicated labs', one in Germany (analytische Laboratorien) and one in Sweden
(Mikro Kemi AB). They both give about the same results. The samples are handled
as hydroscopic, and the drying conditions have varied from 60-100 degrees
centigrade in vacuum with the same results.

Best Regards /jN
