' LABORATORY NARRATIVE TO-14 ' ETIC Engineering Workorder#0101040 ' Sixteen 6 Liter Summa Canister samples were received on January ry 03 2001 The laboratory performed analysis via EPA Method TO-14 using GC/MS in the full scan mode The method involves ' concentrating up to 0 S liters of air The concentrated aliquot is then flash vaporized and swept through a water management system to remove water vapor Following dehumidification, the sample passes directly into the GC/MS for analysis See the data sheets for the' reporting limits for each compound ' During the five point calibration, two low-level standards are used The low-level standard for TO-14- compounds is spiked at 0 5 ppbv and represents the reporting limit for these compounds The low-level standard for the non-TO-14 compounds is spiked at 2 0 ppbv and represents the reporting ' limit for these compounds The TO-14 compounds are present in both standards but are excluded from reporting in the 2 0 ppbv standard since a lower level is already included in the curve ' Method modifications taken to run these samples include Requirement TO-14 ATL Modifications Internal standard retention Not specified Within 0 50 minutes of most recent daily CCV internal ' times standards Internal standard recoveries Not specified Within 40% of the daily CCV internal standard area for blanks and samples Internal standard retention Not specified Within 0 50 minutes of most recent daily CCV internal times standards ' Internal calibration criteria Not specified RSD of 30% or less for standard compounds,40% or less for non-standard and polar compounds Cantinuins calibration Not specified 70- 130% for at least 90% of standard compounds,60- verification criteria 140% for at least 30% of non-standard and polar ' compounds Response factor for Average response Average response factor(ICAL) quantitation tactor(ICAL) I Receivin Notes ' There were no receiving discrepancies ' Analytical, Notes The Methanol standard analyzed on 01/07/01 was one day outside the 3 day hold specified in the TO 14 SOP The standard was recertified on 1/08/Oland met all QC requirements ' Definition of Data Qualifying Flags Seven qualifiers may have been used on the data analysis sheets and indicates as follows B - Compound present in laboratory blank greater than reporting limit(back-round subtraction not In pertormed) ' 7 - Estimated value E - Exceeds instrument calibiation range S - Saturated peak ' Q - Exceeds quality control limits
