General description
Bentazon is a commonly used pesticide which effectively controls weed in paddy fields.
Application
Bentazon has been used as analytical standard in liquid chromatograph with a photodiode array (PDA) detector coupled in series with a mass spectroscopy (MS) detector equipped with an atmospheric pressure electrospray ionization source (ESI) for the determination of bentazon and its transformation products.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
