Diphanamid Separation on Zodiac HST B2 Column

Diphenamid is a pre-emergence herbicide widely used in the cultivation of crops such as tobacco, groundnuts, and tomatoes. For its retention and separation from impurities, Obelisc R and Zodiac HST B2 columns are employed.

Zodiac HST B2 contains embedded basic ion-pairing groups, while Obelisc R features embedded ionic and hydrophobic groups, enabling precise and fine-tuned separations. This LC/MS-compatible method provides a robust and reliable approach for analyzing diphenamid as well as numerous other pesticides.
