A method blank is a laboratory-generated <br /> sample which assesses the degree to which laboratory operations 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 section <br /> C. Laboratory Contr_oLSpike. 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 /> ' Duplicate 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 /> Matrix Spike and Matrix Spike Duplicate Analysis Report <br /> Accuracy is measured by Percent Recovery as in <br /> % recovery = (measured concentration) x,100 <br /> ' (actual concentration) <br /> ' III Analysis Results <br /> Results are on the attached data sheets <br /> 1 <br />
