Software: Bruker Eva 6.0 with ICDD CD-ROM Release 2000. 
Methods: 
Sample1:         Background subtraction 
                        Subfile: Mineral 
                        Offset correction after identification of Quartz 
                        then further identification 
Sample2:         Background subtraction 
                        Subfile: Master, no further constraints 
                        No single phase from the PDF2000 fits, a few phases 
                        highlighted, but chemical data necessary 
Sample3:        Background subtraction 
                        Subfile: Pharmaceutical, no further constraints 
                        No results 
                        Subfile: Master, no further constraints 
                        some results 
                     Comment: There are some matches, which do not match exactly, but are fairly close and I would tell the client that those results could possibly be used to work on the the basic structure of the material. 

Sample4:         Background subtraction 
                        Subfile: Master, constraint no organic phases
