ICP analyses by solution
General sample requirements
1. Rock samples need to be crushed into fine powder, sediment samples need to be dried, 0.5 g sample is normally needed but in extreme case, smaller sample amount is accepted.
2. Water samples (both salt water and freshwater) need to be acidified to pH 1 - 2, normally 100 ml is needed, but depending on analysis required, as low as 10 ml is acceptable.
3. Plant material need to be dried and crushed into fine powder, 1 g sample is needed.
4. Biological tissue samples need to be dried (preferably freeze dried), at least 0.25 g (dry weight) sample is needed, if that is not possible smaller sample can be accepted but client need to talk to AAC staff first.
