Spargero <br /> Analytical Laboratory Divisio <br /> Technokxjy, � Mobile Laboratory Divisiv <br /> Scientific Division <br /> Enwronmental Laboratories <br /> II Qualily Control <br /> A. Pr-lect Specific QC. No project specific QC (i e , spikes and/or <br /> duplicates) was requested <br /> B. Method Blank Results. A method blank is alaboratory-generated <br /> sample which assesses the degree to which laboratory operation and <br /> procedures cause false-positive analytical results for your sample. <br /> No target parameters were detected in the method blank associated ■ <br /> with your sample at the reporting limit levels noted on the data sheets 1� <br /> in the Analytical Results section <br /> C. Laborato Control Spike.ry ,._p A Laboratory Control Spike (LCS) is a <br /> sample which is spiked with known analyte concentrations, and <br /> analyzed at approximately 10% of the sample load in order to <br /> establish method specific control limits The LCS results associated <br /> with your samples are on the attached Laboratory Control Spike and <br /> Laboratory Control Spike Duplicate Analysis Resport <br /> D. Matrix_ Spike Results. A Matrix Spike is a sample which is spiked <br /> with known analyte concentrations, and analyzed at approximately <br /> 10% of the sample load in order to establish method-specific control <br /> limits. The Matrix Spike results associated with your samples are on <br /> the attached Matrix Spike and Matrix Spike Duplicate Analysis <br /> 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 /> 11 <br /> r <br /> 3050 Fite Circle, Suite 112 - Sacramento, California 95827 - (916) 362-8947 • FAX (416) 362-0947 <br />
