Applications:

UV-Vis Spectrum of Diuron

July 12, 2024

UV-Vis Spectrum of Diuron. Absorption Maxima: 212 nm, 250 nm, 287nm.

 

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.

Application Analytes:
Diuron

HPLC Separation of Pesticides, Herbicides, Fungicides and Insecticides on Newcrom BH Column

May 22, 2020


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.

Separation of Diuron on Newcrom R1 HPLC column

February 16, 2018
Separation of Diuron on Newcrom C18 HPLC column

Diuron 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.

HPLC Method for Analysis of Pesticides: Isoproturon, Diuron, Acenaphthene, Carbendazim

July 11, 2017

Isoproturon is an agricultural herbicide with a tendency to adsorb to soils, which leads to it entering bodies of water. In that water, it is highly toxic for algae and oysters, while long term exposure to the pesticide affects the growth of fish. Diuron is a pre-emergent that is used for non-crop areas as well as with many agricultural crops. It has a low acute toxicity to mammals. It can cause irritation of nose and throat.if inhaled and irritation of eyes if comes in contact with the eyes. Acenaphthene is derived from coal tar and has many used such as dyes, pharmaceuticals, insecticides, fungicides, and plastics. It is harmful if ingested, inhaled or comes in contact with skin, and can cause irritations to skin, eyes, upper respiratory tract, and mucous membranes Carbendazim, also known as mercazole, is a broad-spectrum benzimidazole fungicide. It’s used mostly as a worm control agent in places like tennis courts and golf greens. Sometimes it is also used to control plant diseases in cereals and fruits. Primesep 100, a reverse-phase column, contains embedded acidic ionizable groups and can retain Isoproturon, Diuron, Acenaphthene, and Carbendazim. The method is UV compatible and can be used as a general approach for analyzing similar compounds.
