No project specific QC (i.e., spikes and/or <br /> r duplicates) was requested. <br /> L <br /> B. Method Blank Results. A method blank is a laboratory-generated <br /> sample which assesses the degree to which laboratory operations and <br /> L 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 section. <br /> LC. LaboratoryControl I Spike. . 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 method- <br /> specific control limits. The LCS results associated with your samples.are <br /> on the attached Laboratory Control Spike and Laboratory Control Spike <br /> LDuplicate Analysis Report. <br /> D. Matrix Spike Results. A Matrix Spike is a sample which is spiked with <br /> known analyte concentrations, and analyzed at approximately 10% of the <br /> sample load in order to establish method-specific control limits. The <br /> Matrix Spike results associated with your samples are on the attached <br /> L Matrix Spike and Matrix Spike Duplicate Analysis Report. <br /> I Accuracy is measured by Percent Recovery as in: <br /> L % recovery = (measured concentration) x 100 <br /> (actual concentration) <br /> L <br /> III Analysis Results <br /> Results are on the attached data sheets. <br />
