Method Description
USP <561> pesticide testing using liquid chromatography targets polar and thermally labile pesticides that cannot be analyzed by gas chromatography. This method complements GC analysis to provide comprehensive pesticide screening required by USP standards for pharmaceutical and supplement applications. Many modern pesticides require LC analysis due to their chemical properties and stability characteristics.
