                              The "ICP-MS_Solids" worksheet contains all ICP-MS data for solid media. Remember that there should be
                              corresponding entries in the Site and Sample worksheets in the SITE_SAMPLE_TEMPLATE.XLS spreadsheet. This
                              worksheet is for analyses by routine in-house and contract ICP-MS analytical methods, as described on Central Minerals
                              Team analytical chemistry intranet website. Note that there are several In-House Lab variations for this method; choose
                              the correct one (see Method Codes worksheet for more information). Qualified data should be entered as "<0.2" or
                              ">2000" (without quotes, no spaces). The name of the laboratory doing the work is requested because not all analyses
                              are done by the same lab. Pay attention to concentration units.

                              The analytes in this worksheet are sorted first by major/trace element and then alphabetically. Additional analytes can be
                              added as needed. You do NOT have to follow this ordering as long as you provide the following for every variable
                              analyzed by ICP-MS:
                              (1) the analyte
                              (2) concentration units
