Carbofuran Separation on Obelisc R HPLC Column
Carbofuran is one of the most acutely toxic insecticides used on field crops. It is banned in Europe, Canada, and as of 2009 was banned in the United States. The EURL included carbofuran as a target pesticide for the EUPT-CF9. Obelisc R was used to retain carbofuran 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 carbofuran and other phenoxy acids.

Carbofuran Separation on Primesep and Obelisc Mixed-Mode HPLC Columns
Carbofuran is one of the most acutely toxic insecticides used on field crops. It is banned in Europe, Canada, and as of 2009 was banned in the United States. The EURL (European Union Reference Laboratory), included carbofuran as a target pesticide for the EUPT-CF9 a proficiency test for cereals and feedingstuff that require muli-residue methods. Primesep B2 and Obelisc R were used to retain carbofuran 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 carbofuran and other phenoxy acids.

HPLC Separation of Carbofuran on Obelisc R and Primesep 100 Columns
Carbofuran is an insecticide notable for its high toxicity to vertebrates, especially birds; it is one of the most toxic to humans as well. While band in many countries such as the U.S. and Canada, it can be purchased over-the-counter in some countries such as Kenya. Carbofuran was considered a target pesticide by the EURL (European Union Reference Laboratory) for the EUPT-FF9 2015 a proficiency test for the analysis of a over a hundred pesticides. Obelisc R and Primesep 100 were used to analyze carbofuran. Primesep 100 separates by reverse-phase and utilizing embedded acidic ion-pairing groups. Obelisc R uses long hydrophobic chains and multiple ion-pairing groups.

HPLC Separation of Pesticides, Herbicides, Fungicides and Insecticides on Newcrom BH Column
Herbicides are used to control unwanted plants, they are also known as weedkillers. Insecticides are used to kill insects. Fungicides are used to kill parasitic fungi. Pesticide is a more generic term that includes herbicides, fungicides and insecticides in its definition. All are heavily used in agriculture. By using HPLC, many different pesticides can be separated and their retention characteristics controlled using the Newcrom BH mixed-mode column. It can be used with different organic media such as acetonitrile (ACN) or methanol (MeOH). By varying the concentration of organic modifier and using different buffers like sulfuric acid (H2SO4), ammonium formate (AmFm), or formic acid, separation of desired pesticides can be achieved.
