Pesticide Analytical Manual Vol. I APPENDIX I,Transmittal No. 2000-1 (10/1999),Form FDA 2905a (6/92) Appendix I–1,APPENDIX I: PESTDATA,Caution: Use this table only as a quick reference for tentative identification of residues found in samples analyzed by the most commonly,used PAM I multiresidue methods. Always compare the residue to a standard chromatographed in your own gas chromatograph.,Apply appropriate confirmatory tests to verify tentative identification. Note that PESTDATA cannot and does not contain all details;,consult PAM I tables that accompany each method for more definitive information about the behavior of the compound through the,steps of the methods.,NOTATIONS AND ABBREVIATIONS USED IN PESTDATA,(In all categories a hyphen indicates absence of data),Name,Preferred name for each chemical. “*” indicates chemicals with multiple GLC peaks. Chlordane, Strobane, toxaphene and all Aroclors,are listed only in the table ordered by name and do not appear in the tables ordered by relative retention times.,Molecular Formula,Numbers are not subscripted. Averages are used for multicomponent chemicals.,RRT/c,Columns list retention times (relative to chlorpyrifos) on GLC column indicated. Conditions under which these data were gathered are,described in these Section 302 DG modules:,GLC Column Section 302 DG modules,OV-101 DG1-DG5,OV-17 DG13-DG17,OV-225 DG18, DG19,Note that headers in these tables refer to GLC columns by the names used for packed columns, despite DG1-DG19’s descriptions of,wide bore capillary column systems, because so many of these rrts were developed using packed columns. Rrt data for equivalent,packed and capillary columns are expected to be essentially identical and are combined in PESTDATA.,APPENDIX I Pesticide Analytical Manual Vol. I,Transmittal No. 2000-1 (10/1999),Appendix I–2 Form FDA 2905a (6/92),Responses,Data specify column and detector used. Numbers refer to weight (ng) that causes detector response of approximately 50% full scale,deflection (FSD) on the recording device. Response values collected when the detector was combined with a wide bore capillary,column include the notation “(WB).” Codes refer to detectors and operating conditions described in these Section 302 DG modules,except that all response values are based on detector sensitivity of 50% FSD to 1.5 ng chlorpyrifos:,Code Detector Section 302 DG modules,TR tritium electron capture none - obsolete detector,TI thermionic (KCl) none - obsolete detector,FP flame photometric, phosphorus DG2, DG14, DG19,FS flame photometric, sulfur DG15,NI 63Ni electron capture DG1, DG13, DG18,NP nitrogen/phosphorus DG5, DG17,HX electroconductivity (halogen mode) DG3, DG16,HN electroconductivity (nitrogen mode) DG4,MC microcoulometric none - obsolete detector,NOTES: Response values are approximate and can vary dramatically on different chromatographs. Most response values represent,rounded-off or averaged values; some were collected under conditions different from those suggested in references.,Recoveries,Data on the recovery of the compound through several PAM I methods are listed in columns with the following headings. See the,appropriate PAM I table(s) for more details, such as partial recoveries through Florisil.,Heading Common Name PAM I Section PAM I Table,302 Luke (Los Angeles) 302 E1-E3, no cleanup 302-a,303 Mills, Onley, Gaither 303 E1-E5 + C1 or C2 303-a,304 Mills fatty food 304 E1-E5 + C1-C4 304-a,Ethers Florisil elution system 303 C1, 304 C1 and C3 303-a, 304-a,CH2Cl2 alternative Florisil elution 303 C2, 304 C2 and C4 303-a, 304-a,Recovery codes have the following meanings: C: complete (>80%); P: partial (50-80%); S: small (<50%); V: variable; R: recovered but,no quantitative information available; NR: not recovered.,Pesticide Analytical Manual Vol. I APPENDIX I,Transmittal No. 2000-1 (10/1999),Form FDA 2905a (6/92),Molecular RRT/c RRT/c RRT/c,Name Formula OV-101 OV-225 OV-17 302 303 304 Ethers CH2Cl2,Appendix I–3,Appendix I: PESTDATA Chemicals in Order by Chemical Name,Recoveries,* Multipeak chemical.,# Recovery may vary with choice of Florisil elution system; see Tables 303-a, 304-a.,1,1'-(2,2-dichloroethylidene)bis(2- C16H16Cl2O2 2.9 - 3.7 - R - - -,methoxybenzene) Responses:,1,2,3,4-tetrachlorobenzene C6H2Cl4 - - 0.09 - - - - -,Responses: OV-17: NI0.2,1,2,3,5-tetrachlorobenzene C6H2Cl4 - - 0.07 - P # - 6 1,Responses: OV-17: NI0.1,1,2,3-trichlorobenzene C6H3Cl3 0.08 - - - C P 6 1,Responses: OV-101: TR2,1,2,4,5-tetrachloro-3-(methylthio)= C7H4Cl4S 0.49 0.35 0.48 R C - 6 1,benzene Responses: OV-101: NI0.3 OV-17: HX(WB)0.3 OV-225: NI0.3,1,2,4,5-tetrachlorobenzene C6H2Cl4 - - 0.07 - - - - -,Res……
