LABORATORY NARRATIVE <br /> Mod. Method TO-14A <br /> Meinfelder <br /> Workorder# 0305399 <br /> Two I Liter Summa Canister samples were received on May 21, 2003. The laboratory performed the <br /> analysis via Modified Method TO-14 using GUMS in the full scan mode. The method involves direct <br /> injection of up to a 40 mL sample aliquot into a vapor management system. Following dehumidification the <br /> sample passes directly into the GUMS for analysis. See the data sheets for the reporting limits of each <br /> compound. <br /> Requirement TO-14A/15 ATL Modifications <br /> Concentration of IS Spike 10 ppbv(TO-15) 500 ppbv <br /> BFB Acceptance Criteria CLP protocol(TO-15) SW-846 protocol <br /> Sampling Drying System Nafion Dryer(TO-14A) Multisorbent.concentrator <br /> IS RTs TO-15: Within .33 min Within 0.33 min of RT in daily CCV <br /> from most recent <br /> calibration(either <br /> ICAL or daily) <br /> IS Recovery TO-15:Within 40%of Within 40%of CCV recovery for blank and samples. <br /> mean over ICAL for <br /> blanks,and w/in 40% <br /> of daily CCV for <br /> samples <br /> Receiving Notes <br /> There were no receiving discrepancies. <br /> Analytical Notes <br /> There were no analytical discrepancies. <br /> Definition of Data Oualifving Flags <br /> Seven qualifiers may have been used on the data analysis sheets and indicates as follows: <br /> B - Compound present in laboratory blank greater than reporting limit (background subtraction no <br /> performed). <br /> J - Estimated value. <br /> E -Exceeds instrument calibration range. <br /> S - Saturated peak. <br /> Q -Exceeds quality control limits. <br /> U - Compound analyzed for but not detected above the reporting limit <br /> UJ-Non-detected compound associated with low bias in the CCV. <br /> File extensions may have been used on the data analysis sheets and indicates <br /> as follows: <br /> a-File was requantified <br /> b-File was quantified by a second column and detector <br /> rl-File was requantified for the purpose of reissue <br /> Page 2 of 7 <br />
