General description

Chlorsulfuron belongs to the class of sulfonylurea herbicides.

Application

Chlorosulfuron may be used as an analytical reference standard for the determination of chlorosulfuron in:
  • Environmental water samples by magnetic solid phase extraction (MSPE) using multi-walled carbon nanotubes adsorbents combined with high performance liquid chromatography-diode-array-detection (HPLC-DAD).
  • Soya milk samples by QuEChERS (quick, easy, cheap, effective, rugged and safe) extraction and HPLC-DAD as well as HPLC combined with triple quadrupole tandem mass spectrometry (QqQ-MS/MS).
  • Honeybees by dispersive SPE followed by liquid and gas chromatography combined with tandem mass spectrometry (LC-MS/MS and GC-MS/MS) with electrospray ionization (ESI), and multiple reaction monitoring (MRM) detection.
  • Fruits and vegetable samples by methanolic extraction and ultra-HPLC in conjunction with ESI-MS/MS and MRM detection.
  • Cereals by QuEChERS extraction and HPLC coupled to ESI-MS/MS with selected reaction monitoring (SRM) detection.
