Orbitrap GC-MS for Quantitative and Qualitative Multi-residue Analysis of Pesticides
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.
Evaluating Natural Preservatives for Meat Products with Gas and Liquid Chromatography
April 1st 2025A study in Food Science & Nutrition evaluated the antioxidant and preservative effects of Epilobium angustifolium extract on beef burgers, finding that the extract influenced physicochemical properties, color stability, and lipid oxidation, with higher concentrations showing a prooxidant effect.
Rethinking Chromatography Workflows with AI and Machine Learning
April 1st 2025Interest in applying artificial intelligence (AI) and machine learning (ML) to chromatography is greater than ever. In this article, we discuss data-related barriers to accomplishing this goal and how rethinking chromatography data systems can overcome them.
The Benefits of Custom Bonded Silica
April 1st 2025Not all chromatography resins are created equal. Off-the-shelf chromatography resins might not always meet the rigorous purification requirements of biopharmaceutical manufacturing. Custom bonded silica from Grace can address a wide range of separation challenges, leading to real performance improvements.
