DOCUMENT DESCRIPTION

In addition, SW-846 methods, with the exception of required method use for the analysis
of method-defined parameters, are intended to be guidance methods which contain general
information on how to perform an analytical procedure or technique which a laboratory can use
as a basic starting point for generating its own detailed Standard Operating Procedure (SOP),
either for its own general use or for a specific project application. The performance data
included in this method are for guidance purposes only, and are not intended to be and must
not be used as absolute QC acceptance criteria for purposes of laboratory accreditation.
