Pre-treatment versus direct injection – that is the question posed in the application note, “The Detection of Acidic Herbicides and Phenyl Ureas by LC-MS/MS with Large Volume Injection and Automated Column Switching.” It’s just one of the dozens of articles you will find within the Environmental Compendium (pages 1 to 4, pesticides) now available for download.Download Compendium >
Here’s the thing with Pesticides. They are taking a hit for their toxic pervasiveness to wildlife and suspected hormone-disrupting qualities. A problem as they find their way into drinking water via agriculture runoff or rogue dumping. This is not just in happening in Europe but the world over. However, since this particular report focuses on the UK, here is some background information on the state of water testing within the region. According to a Eurostat Report, seven percent of groundwater stations have reported excessive levels of one or more pesticides. However, as this application note points out, detection improvements are correlating with lowered acceptable limits. Hence, the need for a testing method that removes both cost and time associated with solid phase extraction and/or liquid/liquid extraction traditionally used for GC-MS analysis.
To give you an idea of what you will find not only in this study but throughout the environmental compendium, we’ve outlined some key points. For instance, you will discover how river and groundwater samples were obtained, filtered and directly injected into the LC-MS/MS system. Researchers thus follow up with graphics and content about:
Real-life scenarios and enforcing safety is a theme for the environmental compendium, and this application note demonstrates its effectiveness as the method is sensitive enough to be applied to U.K. surveillance work.
Trifluoroacetic acid (TFA) is emerging as one of the most concerning ultrashort-chain PFAS in Europe’s food supply – particularly in cereals, a staple consumed daily by millions. A report from PAN Europe reveals a widespread and largely unmonitored contamination trend that raises serious questions about food safety, regulatory blind spots, and future monitoring strategies.
PFAS analysis is complex, but expert guidance doesn’t have to be. In this episode of our ‘Ask the PFAS expert series’, we’re joined by Michael Scherer, Application Lead for Food and Environmental, to answer the most pressing questions in PFAS analysis. From why LC-MS/MS systems are the gold standard for analyzing diverse PFAS compounds, to which EU methods deliver reliable results for drinking water, and to practical steps to prevent contamination, Michael shares actionable insights to help laboratories achieve accuracy, consistency, and confidence in their workflows.
During an LC-MS/MS experiment, traditional fragmentation techniques like collision-induced dissociation (CID) have long been the gold standard. Electron-activated dissociation (EAD) is emerging as a transformative tool that enhances structural elucidation, particularly for complex or labile metabolites.
