Laboratories analyzing food commodities for glyphosate and associated highly polar anionic pesticides can face complex and time-consuming workflows. Waters direct analysis application solutions deliver retention times you can rely on, separation power to avoid false detections, and sensitivity to exceed current regulatory requirements.
Using the combination of Waters Anionic Polar Pesticide column, Atlantis BEH C18 AX, and ACQUITY BEH Amide columns on ACQUITY UPLC Systems coupled with Xevo TQ Absolute or Xevo TQ-S micro MS, you can detect, quantify, and identify residues with confidence. The interpretation of data and full workflow is supported within waters_connect for Quantitation and can be streamlined with support from our expert application chemists.

Achieve robust MS sensitivity with the Xevo TQ-S micro, a compact tandem (triple) quadrupole mass spectrometer with reliable performance, a wide dynamic range, and high data acquisition rates.
Achieve and maintain high performance and productivity with significantly increased sensitivity for negative ionizing compounds with the Xevo TQ Absolute, our compact, sustainable tandem quadrupole mass spectrometer.
Improve your resolving power, lower your system volume, and achieve the tallest, sharpest peaks with the ACQUITY UPLC I-Class PLUS System to maximize the sensitivity of your methods, enhance the characterization of your samples, and improve your productivity.
Example chromatography of the 1st and 200th injection (blue and red traces, respectively) of an organic wheat flour matrix standard, 0.02 mg/kg (5 ng/mL in vial concentration). These were a set of continuous injections without any intervention by the operator. Retention time RSDs for all compounds across the whole run were within 0.3%.
Chromatograms of chlorate, perchlorate, and bromate from the analysis of matrix-matched standards (infant formula) at 0.1 µg/kg.
Chromatograms of the anionic polar pesticide and metabolites from the analysis of a cucumber matrix standard at 1 µg/kg (in vial concentration 0.5 ng/mL).
Summary of the measured recoveries (%) and repeatability (%RSDr) from the analysis of spikes from cucumber, rice, soyabean, and milk.
Typical calibration graphs for anionic polar pesticides over the range in 0.005–0.20 mg/kg (5–200 ppb), in cucumber.
