In recent years, high performance liquid chromatography (HPLC) has grown in popularity as a determinative step for residue analysis, until today it is accepted as complementary to the more traditional gas liquid

Caution: Use this table only as a quick reference for tentative identification of residues found in samples analyzed by the most com￾monly used PAM I multiresidue methods. Always compare the residue to a standard chromatographed in your own gas chromatograph

1 Codes: C: complete (>80%); P: partial (50-80%); S: small (<50%); V: variable (approximate percentage when known); R: recovered but no quantitative information available; NR: not recovered

N-methylcarbamate insecticide residues, including carbamate metabolites, are ex￾tracted with methanol. The extract is cleaned up by partitioning and column chromatography on a charcoal/Celite column. Residues are selectively determined

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

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)
