UV-Vis Spectrum of Fluroxypyr-Meptyl
July 15, 2024
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.

HPLC Method for Separation of Fluroxypyr-meptyl on Primesep 100 by SIELC Technologies
Separation type: Liquid Chromatography Mixed-mode
Fluroxypyr-meptyl is a herbicide used for the control of broad-leaved weeds in cereals, pastures, and non-crop areas. It belongs to a class of herbicides known as synthetic auxins.
Auxins are a class of plant hormones which are involved in the regulation of plant growth. Synthetic auxins like fluroxypyr mimic the action of natural auxins but disrupt the normal growth processes in the target plants, leading to their death.
Fluroxypyr-meptyl is effective against a range of weed species, including some that are resistant to other types of herbicides.
This herbicide can be retained and analyzed on a mixed-mode Primesep 100 column with a mobile phase consisting of water, Acetonitrile (MeCN), and Sulfuric acid (H2SO4). This analytical method can be UV detected at 220 nm with high resolution and peak symmetry.
LOD was determined for this combination of instrument, method, and analyte, and it can vary from one laboratory to another even when the same general type of analysis is being performed.

Separation of Fluroxypyr-meptyl on Newcrom R1 HPLC column
February 16, 2018
Fluroxypyr-meptyl 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.
