No other pesticide has courted more media attention and controversy in recent months than glyphosate, with governments and national agencies debating its use and health effects. The following links just show some of the media attention this organophosphorus compound has received:

However irrespective of whether it poses a risk or not the analysis of glyphosate and other polar compounds in food and beverage products has been a challenge. Attaining the required sensitivity, dealing with complex matrices and sample prep can put a serious strain and demand on your laboratory. A common practice for the analysis of glyphosate and the other associated polar compounds such as AMPA, Glufosinate, and MMPA is to derivatize the samples during the preparation.
The derivatization method may be effective however there is a serious efficiency problem associated with it, the time it takes the analysts to prep and extract the sample. Derivatization can be a time-consuming procedure and can, therefore, affect a lab’s productivity, turnaround, and margins.
In a recent presentation, on the QTRAP® 6500+ System, we conducted an in-depth evaluation into the Quantitation of Underivatized Glyphosate and Other Polar Pesticides. This comprehensive study details the various techniques and LC conditions that we tested on a variety of matrices. In this study, we show how the SelexION® reduces interferences and can meet your required levels of sensitivity.
The Echo® MS+ system is a novel platform for Acoustic Ejection Mass Spectrometry (AEMS) and combines the speed of acoustic sampling with the selectivity of mass spectrometry. This platform has been designed for high throughput analysis of small and large molecules. The technology combines Acoustic Droplet Ejection (ADE), an Open Port Interface (OPI) and could be coupled with the SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system.
The Echo® MS+ system comprises of an open-port interface (OPI) and acoustic droplet ejection (ADE) module which could be coupled with a mass spectrometer. The mass spectrometer could either be a SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system. This non-liquid chromatography based; high-throughput screening platform enables rapid analysis of compounds at speeds of up to 1 sample/second.
The ability to consistently achieve reproducible results on many complex samples across multiple days is critical to a routine clinical laboratory. Laboratories relying on analytical instrumentation require stability and robustness to perform a variety of screening and confirmatory assays with confidence. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) has become the preferred analytical method in the clinical laboratory to reliably perform clinical testing as it provides best-in-class performance and reliability for the most challenging assays. LC-MS/MS offers the required levels of sensitivity and specificity for the detection and quantitation of molecules from complex biological samples, helping laboratories deliver highly accurate data for a variety of clinically relevant analytes across a wide range of assays.
