CRA MEMORANDUM Page <br /> MS and MSD is used to assess analytical precision. If the original sample concentration is significantly <br /> greater than the spike concentration,the recovery is not assessed. <br /> The MS/MSD samples were spiked with all compounds of interest. All percent recoveries and RPD values <br /> were within the laboratory control limits, demonstrating acceptable analytical accuracy and precision. <br /> 13.0 Target Compound Identification <br /> To minimize erroneous compound identification during organic analyses, qualitative criteria including <br /> compound retention time and mass spectra, if applicable,were evaluated according to the identification <br /> criteria established by the methods. <br /> 14.0 Conclusion <br /> Based on the assessment detailed in the foregoing,the data summarized in Tables 1-2 are acceptable <br /> without qualification. <br /> EQUAL EMPLOYMEM OPPOMNIW EMPLOYER <br />
