Applications:


Pirimicarb Separation on Obelisc R HPLC Column
Pirimicarb is a carbamate pesticide used mostly to control aphids on non-food crops. The EURL included pirimicarb as a target pesticide for the EUPT-CF9. Obelisc R was used to retain pirimicarb and separate it from impurities. 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 pirimicarb and other carbamate pesticides.

Pirimicarb Analysis on Obelisc and Primesep Mixed-Mode HPLC Columns
 
Pirimicarb is a carbamate pesticide used mostly to control aphids on non-food crops. The EURL included pirimicarb as a target pesticide for the EUPT-CF9. Obelisc R was used to retain pirimicarb and separate it from impurities. Primesep B2 and Obelisc R were used to retain pirimicarb and separate it from impurities. Primesep B2 contains embedded basic ion-pairing groups and 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 pirimicarb and dozens of other pesticides.

HPLC Retention of Pirimicarb on Primesep 100 and Obelisc R
  Pirimicarb is an insecticide that controls aphids on vegetable, cereal, and orchard crops. A carbamate insecticide, pirimicarb inhibits activity of the hydrolase acetylcholinesterase. Pirimicarb is a target pesticide in the EURL (European Union Reference Laboratory) EUPT-FF9 2015 a proficiency test for the analysis of a over a hundred pesticides.  Primesep 100 and Obelisc R were used to retain pirimicarb and separate it from impurities. Primesep 100 contains embedded acidic ion-pairing groups and 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 pirimicarb, other organophosphate insecticides, and dozens of other pesticides.
