Method Blank Results. 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 Control 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 />' Duplicate Analysis Report <br /> D.
