' A method blank is a laboratory-generated I <br /> sample which assesses the degree to which laboratory operations erations and <br /> procedures cause false-positive analytical results for your sample. <br /> No target parameters were detected in the method blank associated with <br /> your sample at the reporting limit levels noted on the data sheets in the <br /> ! Analytical Results seciion. <br /> C. Laboratory Control S' ike. A Laboratory Control Spike (LCS) is a <br /> sample which is spiked with known analyte concentrations, and analyzed <br /> at approximately 10% of the sample load in order to establish <br /> p method- <br /> specific control limits. The LCS results associated with your samples are 4 <br /> on the attached Laboratory Control Spike and Laboratory Control Spike <br /> Duplicate Analysis Report. <br /> D. Matrix Sl2ike Results.: A Matrix Spike is a sample which is spiked with <br /> known analyte concentrations, and analyzed at approximately 10% of the <br /> t sample load in order toy establish method-specific control limits. The <br /> Matrix Spike results associated with your samples are on the attached <br /> Matrix Spike and Matrix Spike Duplicate Analysis Report. <br /> Accuracy is measured by Percent Recovery as in: l <br /> % recovery = (measured concentration) x 10 <br /> (actual concentration) <br /> L <br /> t III Analysis Rt$ults <br /> Results are on the attached data she ets. <br /> :l <br /> ' E <br /> 'f <br /> __�7 (9-46) 362-894 a F (916) j62­59417I <br />
