I'm trying to respond to a request for a reprint. It gives me a message in a red box --"An error occurred." Nothing more. Why?

I have the file, and prefer to send it privately (because I'm not a lawyer, and don't really know what permissions I have to send or post it publicly). Please advise if possible.

ICP method for trace analysis of metals (including Hg) after sample digestion.

CVAAS method for Hg determination (analyzers dedicated only to mercury)- sample digestion is not necessary.

Rex Zietsman

Depends on what your system operating parameters are. Normal downdraft units run under slight vacuum, about -0.5kPa, but large pressurised oxygen gasifiers can be up to 20 barg.

Davide Bergna

It depends on what kind of gasifier you are using. Can be from slight vacuum to about 30 MPa if you are using super-critical water gasification.
