Glyphosate
Glyphosate [(N-phosphonomethyl)glycine] is a non-selective broad-spectrum herbicide that is extensively used in agriculture. The biodegradation of Glyphosate (GLY) in the environment leads to aminomethylphosphonic acid (AMPA) as well as glufosinate.

Analysis of Glyphosate in Beers
AFFINIMIP® SPE Glyphosate has been successfully used for the enrichment and cleanup of glyphosate, AMPA, and glufosinate from blond beer and dark beer. AFFINIMIPÒ SPE Glyphosate demonstrated a high selectivity for the three molecules, giving good recoveries. In addition, the protocol has shown a good reproducibility with a relative standard deviation between 5% and 9% over 7 samples.

Analysis of Glyphosate in Sea Water by AFFINIMIP® SPE Glyphosate
This application note describes the purification of glyphosate, AMPA, and glufosinate with 500mL of sea water at 200ng/L using AFFINIMIP® SPE Glyphosate via an automate Gilson 274 ASPEC Large Volume System. The method is done WITHOUT DERIVATIZATION saving a lot of time and trace analysis was done by LC-MS/MS. Recovery higher than 90% were observed for glyphosate and AMPA with a good repeatability.

Cleanup and concentration of glyphosate and AMPA from 500mL of sea water was successfully carried out with AFFINIMIP® SPE Glyphosate with an excellent yield without derivatization. With the proposed method, limit of detection of 0.12 and 0.22 ng/L could be reached for Glyphosate and AMPA.
The challenge of detecting the herbicide glyphosate and its metabolite AMPA in seawater – Method development and application in the Baltic Sea; Marisa A.Wirth, Detlef E.Schulz-Bull, Marion Kanwischer, Chemosphere, Volume 262, January 2021, 128327, https://doi.org/10.1016/j.chemosphere.2020.128327
AFFINIMIP® SPE Glyphosate was tested on different water matrices (mineral, groundwater, geothermal and sea). The protocol was first applied to mineral water spiked by GLY and AMPA at environmental concentration levels (25-750 ng L−1) using UPLC-MS after derivatization of GLY and AMPA by 9-fluorenylmethylchloroformate. The linear correlation between concentrations measured with and without SPE on MIP was proved. Furthermore, other extractions showed that high concentrations of metal ion interferents (lead(II), cadmium(II), and zinc(II)) in groundwaters did not reduce SPE performance of the MIP. Then, concentration assays were undertaken and brought noteworthy results, such as the recovery of 80% GLY and AMPA from groundwater spiked at 10 ng L−1 and concentrated 100 times. For this purpose, ion exclusion chromatography hyphenated to mass was applied without previous derivatization of the analytes. The same concentration factor and analytical method were applied to 100 ng L−1 spiked sea water with recoveries of 96% for GLY and 121% for AMPA.
