Description

General description

Vamidothion belongs to the class of organophosphorus pesticides (OPs) which act as cholinesterase inhibitors and are utilized for protection of crops against spiders, mites, aphids, beetles, caterpillars, etc.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Vamidothion may be used as an analytical reference standard for the determination of the analyte in:

• Aqueous samples by direct injection using liquid chromatography–tandem mass spectrometry (LC-MS/MS) as well as hydrophilic interaction liquid chromatography (HILIC) with MS/MS.
• Biological samples by gas chromatography in conjunction with mass-selective detection (GC-MSD).
