HPLC Separation of Pesticides on Newcrom B Column
February 3, 2020
HPLC Method for Metalaxyl (UV), Propoxur, Paclobutrazol, Abamectin, Propanil, Iprodione, Chlorpyrifos-methyl (Dursban), Pentachlorophenol, Fenvalerate on Newcrom B by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Metalaxyl (UV), Propoxur, Paclobutrazol, Abamectin, Propanil, Iprodione, Chlorpyrifos-methyl (Dursban), Pentachlorophenol, Fenvalerate.
Metalaxyl, also known as methyl N-(methoxyacetyl)-N-(2,6-xylyl)-DL-alaninate, is a systemic fungicide with the chemical formula C15H21NO4. It is used to control Pythium and Phytophthora in vegetables. It has suffered a resistance problem going back to the 1980s.
Propoxur is a non-systemic insecticide produced from catechol with the chemical formula C11H15NO3. It has a variety of uses from turf, forestry, and agricultural pests to household pests and fleas.
Paclobutrazol (PBZ) is a synthetic triazole compound with the chemical formula C15H20ClN3O. It is used to control plant growth as an antagonist of the plant hormone gibberellin. Through reducing reducing internodal growth, it causes stronger stems, greater root growth, and earlier fruitset. It can also reduce frost sensitivity in plants.
Abamectin is a insecticide with the chemical formulas C48H72O14 and C47H70O14. It is also used to control fire ant populations. In veterinary cases, it is used to deworm horses as well as an antihelmintic.
Propanil is a contact herbicide with the chemical formula C9H9Cl2NO. It is one of the most widely used herbicides in America. It works as an inhibitor of photosynthesis and CO2 fixation in weeds.
Iprodione is a hydantoin fungicide and nematicide with the chemical formula C13H13Cl2N3O3. It is used on a wide variety of crops that are affected by fungal diseases such as botrytis bunch rot, brown rot, and Sclerotinia. Approval of using it is different across the world.
Dursban is a highly toxic organophosphate with the chemical formula C9H11Cl3NO3PS. It works through interrupting the electrochemical processes in nerves. This leads to a build-up of acetylcholine, which leads to paralysis and eventual death.
Pentachlorophenol is a manufactured chemical with the chemical formula C6HCl5O. It is most often used as herbicide, insecticide, fungicide, algaecide, and disinfectant. Exposure to it can cause damage to liver, kidney, blood, lungs, eyes, skin, and mouth. It is classified as a probable human carcinogen.
Fenvalerate is synthetic pyrethroid insecticide with the chemical formula C25H22ClNO3. It is used against a wide range of pests, partially due to it’s moderate mammalian toxicity following short-term and acute exposure. It is the most toxic to bees and fish. Upon contact, it may irritate skin and eyes.
Metalaxyl (UV), Propoxur, Paclobutrazol, Abamectin, Propanil, Iprodione, Chlorpyrifos-methyl (Dursban), Pentachlorophenol, Fenvalerate can be retained and analyzed using the Newcrom B stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a formic acid buffer. Detection is performed using UV.

Separation of Iprodione on Newcrom R1 HPLC column
February 16, 2018
Iprodione can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.
Application Column
Newcrom R1
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
