Glyphosate a broad-spectrum herbicide (e.q. known as “roundup”) is worldwide primarily used in agriculture and horticulture. It is used in different formulations, consisting of the effective glyphosate(-anion) and a corresponding cation. Trimethylsulfonium(-cation) (trimesium) is a possible counter ion for the glyphosate(-anion). The detection of trimesium could be an indication for a glyphosate treatment.
The PiCA GmbH has integrated the analysis of trimesium in their portfolio and can offer you the determination in tea, hops and other matrices.
