Descripción general

Metazachlor is an α-chloracetamide derivative which is widely used as a herbicide for weed control in the cultivation of crucifers such as rape.

Aplicación

Metazachlor may be used as an analytical standard for the determination of metazachlor in:
  • Natural water samples by high performance liquid chromatography-electrospray-tandem mass spectrometry (HPLC-ESI-MS/MS).
  • Plant foodstuffs by capillary gas chromatography equipped with electron capture detector (ECD) as well as nitrogen phosphorus detector (NPD) followed by MS analysis in electron impact ionization (EI) mode.
  • Drinking and related waters by solid phase extraction (SPE) followed by GC-EI-MS.
  • Wastewater samples by SPE and subsequent analysis with ultra-performance liquid chromatography combined with time of flight mass spectrometry (UPLC-TOF-MS).

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
