Paragon Analytics <br />IV~ETALS CASE NARRATIVE <br />CEMEX, Inc. <br />Order Number - 0407037 <br />1. This report consists of 1 water sample. <br />2. The sample was received intact on 07/02104. The temperature of the sample upon <br />receipt was ambient. <br />3. The sample had not been preserved for the requested analyses. The sample was <br />preserved with nitric acid to a pH less than two prior to analysis. <br />4. The sample was prepared for analysis based on Methods for the Chemical <br />Analysis of Waters and Wastes (MCAWW), May 1994 procedures. <br />For analysis by Trace and conventional ICP and ICP-MS, the sample was digested <br />following method 200.2 and PA SOP 806 Rev. 10. <br />The sample was prepared for ICP-MS analysis of selenium bypassing the sample <br />and associated QC through a cation exchange column. <br />For analysis by Cold Vapor AA (CVAA), the sample was digested following <br />method 245.1 and PA SOP 812 Rev. 10. <br />5. The sample was analyzed following Methods for the Chemical Analysis of Waters <br />and Wastes (MCAWW), May 1994 procedures. <br />Analysis by Trace ICP followed method 200.7 and PA SOP 807 Rev. 9. <br />The relationship between intensity and concentration for each etement is <br />established using at least four standards, one of which is a blank solution. The <br />equation which relates intensity to concentration is: <br /> <br />where: I =intensity <br />= concentration <br />Ao =offset coefficient <br />At =gain coefficient <br />Ofl~~ l <br /> <br />PARAGON ANALYTICS <br />
