 DEC ABR OM OD IPHEN YL OX IDE: ME TH OD 2559, Issue 1, dated 1 5 Ma rch 2003 - Page 4 of 4 EVALUATION OF METHOD: This method was not evaluated with laboratory generated air sam ples. All of the recovery and storage study determinations have been performed with laboratory spiked filters in the development of this method. Air was not pulled throug h the filters prior to analysis. The LO D/LO Q values are 1.0 µg/sa m ple and 3.3 µ g/s am ple res pectively, based on a liquid standard calibration curve. Reco very of spiked quartz fiber filters rang ed from 94.5% to 104.2% for an alyte quantities of 2.6 3 to 25.1 µg/filter using liquid standa rds as the sp iking solution. A thirty day storage stability study of DBDPO spiked on quartz fiber filters indicates that the recovery of the ana lyte at a level of 5.01 :g/filter (N=12) is 103.0%. The sam ples were stored in a closed cardboa rd container at roo m tem pera ture fo r the duration of the study.
