USP <561> Pesticide Residue testing: Do you have the full picture?
Pesticide residue testing screens botanical and supplement ingredients for agricultural chemicals that can persist in raw materials and finished products. Advanced Laboratories runs a full USP <561> screen across 3 instruments and 4 validated methods, not a single-method shortcut, giving supplement and food manufacturers defensible, accredited results that hold up to scrutiny.
accredited results that hold up to scrutiny.
Test for Pesticides Across the Full USP <561> List
You can’t manage a contaminant you didn’t test for. Many labs screen only a subset of pesticides; we test the complete USP <561> target analyte list, so you get more confidence, deeper insight, and better risk management across your formulations and supply chain.

GC-MS/MS
Gas Chromatography–Tandem Mass Spectrometry (GC-MS/MS) handles thermally stable, volatile, and semi-volatile compounds, with low detection limits for organochlorines like DDT and chlordane and high specificity in complex botanical matrices.
UPLC-MS/MS
Ultra-Performance Liquid Chromatography–Tandem Mass Spectrometry (UPLC-MS/MS) targets polar and thermally labile compounds that degrade under heat or resist volatilization, including many organophosphates and carbamates.
GC-MS
Some USP <561> analytes need dedicated workflows. Gas Chromatography–Mass Spectrometry (GC-MS) runs inorganic bromide and dithiocarbamates (measured as CS₂) under separate, chemistry-specific conditions.
Why Our Pesticide Testing Laboratory Goes Further

We test food, powders, capsules, tablets, and liquids.
About 20 grams is the optimal sample amount for pesticide testing.
