Hi River,

I have analysed anhydrite without any problems using CF-IRMS. I think it 
will even combust more easy than barite which is very stable. But you 
have to take care with the cristal water in the gypsum. That might 
affect the analyse: peak tailing because of H2SO3 forming. You might 
want to get rid of the water first before combusting.

regards,
Arnold
