General description

Glufosinate-ammonium is a phosphinic acid analog of glutamic acid.


Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Glufosinate-ammonium may be used as a reference standard for the determination of the analyte in:
  • Human serum samples by mixed-mode solid-phase extraction (SPE), tert-butyldimethylsilyl (t-BDMS) derivatization and gas chromatography-mass spectrometry (GC-MS) operating on electron impact (EI) mode of detection.
  • Water samples by ion-exchange cleanup and derivatization followed by analysis using GC coupled to tandem mass spectrometry (MS/MS) equipped with EI mode of detection.
  • Finnish arable soils by high performance liquid chromatography combined with fluorescence detection (HPLC-FLD).
