Q&A with Stuart Adams

By Sponsor's Content

Some polar ionic pesticides, such as glyphosate, glufosinate, and chlorate and their associated metabolites, residues of polar ionic compounds, are usually often extracted using acidified solvents as used in the so-called Quick Polar Pesticides Extraction (QuPPe) method. This method, which was developed by the European Reference Laboratory for single residue methods, does not incorporate either solvent partitioning or clean-up steps. Thus, the extracts can contain high amounts of co-extracted matrix compounds and be are difficult to analyze. To obtain sufficient chromatographic retention and acceptable peak shapes, individual extracts have to be analyzed multiple times using different chromatographic columns and conditions. Suppressed ion chromatography coupled to mass spectrometry has a number of advantages in the analysis of ionic pesticides. In this interview, Dr. Stuart Adams discusses his thoughts on the use of ion-chromatography in food control laboratories and, especially for the analysis of polar ionic pesticides.

Q&A with Professor Amadeo Fernandez-Alba

By Thermo Fisher Scientific

The introduction of more affordable high resolution, accurate mass (HRAM) mass spectrometry technology coupled to liquid chromatography (LC) brings a new level of performance and flexibility in full scan and MS/MS acquisition modes and perfectly complements recent developments in GC-HRAM technology. Together these technologies provide truly comprehensive workflow solutions for pesticides residues analysis with the capability of performing simultaneously quantitative target residues whilst screening for pesticides not expected to be present in the samples; all at low ng/g concentrations, in complex sample types, and in a single analysis. These developments place a lot of analytical power into the hands of the residues chemists, but which operational parameters do they need to select to harness the power to provide most the most effective residues analysis? In this Q & A, Prof. Amadeo Fernandez-Alba discusses his thoughts on the use of HRAM in food control laboratories

Orbitrap GC-MS for Quantitative and Qualitative Multi-residue Analysis of Pesticides

By Sponsor's Content

The recent introduction of high resolution, accurate mass (HRAM) OrbitrapTM technology coupled to GC brings a new level of performance and flexibility in full scan acquisition and more. Comparable sensitivity and selectivity of triple quadrupole GC-MS/MS, but with broad scope, and the capability for simultaneous targeted and non-targeted analysis of pesticides at low ng/g concentrations, in complex sample types. In this Q & A, Paul Silcock discusses the story so far, around the use of Orbitrap GC-MS for quantitative and qualitative multi-residue analysis of pesticides.

Looking for What We Know About and What We Don’t in Drinking Water

By Sponsor's Content

This podcast will explore the latest developments in the analysis of contaminants of emerging concern in drinking water. We will explore the requirements and results from the EPA’s Unregulated Contaminant Monitoring Rule 3 program for Perfluorinated organics, and hormones. After a brief overview of the EPA analytical techniques, we’ll take a look at new technology and ask how it compares for both and if it can find compounds we didn’t even know were there.

Hormone Analysis by LC–MS and Water Impact

By Sponsor's Content

The increased use of hormone-based therapies in health care throughout the world has resulted in hormones finding their way into municipal water supplies. The potential health risks of unintended consumption of hormones through drinking water have significantly increased the interest in identifying these compounds in our water supplies. The Milli-Q system incorporates a combination of purification processes that provides ultrapure, hormone-free lab water for the LC–MS techniques used for interference-free analysis of these contaminants.

UCT A 30 Year Tradition of Excellence in Sample Preparation

By Sponsor's Content

Since their beginnings in 1986, UCT has evolved into a major competitor in the field of silica based solid phase extraction technology. The first to pioneer commercially available ‘mixed-mode’ SPE products, 30 years later UCT is still optimizing sample analysis for forensic, pharmaceutical, clinical, environmental and agricultural laboratories. Michael J. Telepchak, founder and CEO UCT, Inc., has laid the foundation for this powerful technology and has truly served as a catalyst for its transformation from a novel technique to an industry gold standard. From fundamental chemistry to manufacturing and business development, he has bared witness to all facets of the evolution of solid phase extraction and will speak on the monumental impact it has made on the scientific community.

Analytical Challenges in Measuring Migration from Food Contact Materials

By Sponsor's Content

Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.
