Pesticides Test - USP <561> - LC/TQ

Method Description

USP 561 involves the analysis of pesticides in articles of botanical origin using Liquid Chromatography with Tandem Mass Spectrometry (LC-TQ). This method employs a comprehensive approach to extract and separate pesticides, followed by sensitive quantification using tandem mass spectrometry. The LC-TQ technique ensures accurate identification and quantification of pesticide residues in botanical samples, contributing to product safety and quality. It is a critical tool in pharmaceutical and herbal industries, meeting the stringent requirements outlined by the United States Pharmacopeia (USP) for the analysis of pesticides in botanical articles, thereby safeguarding the integrity of botanical products intended for human consumption or medicinal use.

Additional Information
If an incurred residue is detected, it must be validated prior to being reported as a verified residue. A non-verified residue is a presumed detection or estimated concentration. The concentration reported could change with further validation work. Validation of a non-verified residue can be requested within 30 days from the time the residue is reported. Validation testing has a cost of $213 for up to five analytes. Samples will be reported as follows: see chart
