Glyphosate, a Polar Pest Put to Test

Jun 20, 2016 | Blogs, Environmental / Industrial, Food / Beverage | 0 comments

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.

 

Telling the PFAS story with pine needles

As an ever-expanding group of chemicals, per- and polyfluoroalkyl substances (PFAS) require novel techniques to monitor their current and historical presence in the environment. Concerns over exposure to PFAS chemicals continue to grow, with some having known toxic characteristics and the potential effects of others remaining unknown.1 In addition, while PFAS are one of the most persistent synthetic chemicals to date, most of them hardly degrade in the environment.2 So, how long do traces of PFAS last in our environment? Two tools used to help answer this question are active samplers and passive samplers.

Back to the new basics: Part 3 | LC vs. LC-MS and what it means for your lab

In this final installment of our “Back to the new basics” series, we take one more look at analytical techniques and best practices in the lab, and opportunities to improve efficiency. Here, we explore the basic principles of high-performance liquid chromatography (LC) and liquid chromatography mass spectrometry (LC-MS), and how these techniques can affect a lab’s efficiency and productivity.

Meat vs plant based. What is the best option?

As we become more conscious about the planet, healthier lifestyles and our duty to protect the environment, attitudes and behaviours are shifting when it comes to food consumption.
