  • module 1: ethephon, glyphosate, AMPA, trimesium, glufosinate.
  • module 2: chlormequat, mepiquat, diquat, paraquat.
  • module 3: quaternary ammonium compounds BAC C-8 to C-18, DDAC C-8 to C-12.
  • module 4: ethylene oxide / 2-chloroethanol.

A powder of milled psyllium seed husks, spiked and unspiked, is provided as test material and blank material.

The analytical data are assessed with respect to
