The result for each analyte is <br />a combined concentration. <br />Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. <br />LCS(D) - Laboratory Control Sample (Duplicate) <br />MS(D) - Matrix Spike (Duplicate) <br />DUP - Sample Duplicate <br />RPD - Relative Percent Difference <br />NC - Not Calculable. <br />SG - Silica Gel - Clean -Up <br />U - Indicates the compound was analyzed for, but not detected. <br />N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for <br />each analyte is a combined concentration. <br />Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. <br />TNI -The NELAC Institute. <br />ANALYTE QUALIFIERS <br />D5 The sample was re -weighed into a new container because the sample weight in the original container exceeded the <br />method specifications. <br />S4 Surrogate recovery not evaluated against control limits due to sample dilution. <br />REPORT OF LABORATORY ANALYSIS <br />This report shall not be reproduced, except in full, <br />Date: 03/01/2019 10:18 AM without the written consent of Pace Analytical Services, LLC.
