The expressed purpose of the Pesticide Analytical Manual is to publish analytical methodology used by the FDA in enforcing pesticide tolerances. To understand FDA’s application of methodology published in the manual, it is important to
Transmittal No. 96-E1 (9/96) Form FDA 2905a (6/92) INDEX: METHODS–1 Pesticide Analytical Manual Vol. I INDEX: METHODS Index to PAM I Methods, by Chemicals Tested for Recovery Codes: C: complete (recovery); P: partial; S: small; V: variable; R: recovered; NR: not recovered
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
Recovery of Chemicals Through Method 401 (E1-E2 + C1 + DL1) (methanol extraction, cleanup with partitioning and charcoal/Celite column, HPLC with post-column derivatization and fluorescence detection)
Pesticide multiresidue methods (MRMs) are capable of simultaneously determining more than one residue in a single analysis; this multiresidue capability is provided by a GLC or HPLC determinative step that separates residues from one another before detection. The MRM concept is raised to a higher dimension when a single extract is examined with more than one chromatographic determinative
