Nabam Analysis on Mixed-Mode HPLC Columns

 

Nabam is a di-thiocarbamate fungicide which is used on soils and leaves to protect from a variety of diseases on fruits, vegitables, field crops, and turf. Obelisc R and Primesep B2 were used to retain nabam and separate it from impurities. Primesep B2 contains embedded basic ion-pairing groups while Obelisc R contains embedded ionic and hydrophobic groups which can assist in fine tuning separations. Method is LC/MS compatible and can be used as a general approach for analyzing nabam and dozens of other pesticides.
