HPLC – MS Method for Analysis of Diquat on Obelisc R Column
Diquat is a non-selective contact herbicide used in agriculture and landscaping. It’s known for its effectiveness in controlling a wide range of weeds and plants.
diquat is a potent herbicide used for controlling a broad spectrum of weeds and as a desiccant in agriculture. While effective, its toxicity and environmental impact necessitate careful handling and adherence to regulatory guidelines.
Diquat can be retained and analyzed on a Obelisc R mixed-mode stationary phase column using an isocratic analytical method with a simple mobile phase of water, Acetonitrile (MeCN), and a ammonium format as a buffer. This analysis method can be detected an Evaporative Light Scattering Detector (ELSD), or any other evaporative detection method (CAD, ESI-MS)
