A Method for Analysis of Vanillic Acid and p-Hydroxybenzoic Acid in Polar Ice Cores

This webinar will provide an overview of the analysis of vanillic acid and p-hydroxybenzoic acid at parts per trillion levels in polar ice core samples using IC with MS/MS detection. Measurements taken from a Siberian ice core will be shown as an example application of this method.

Beyond Basic DIA - New Workflows using Orbitrap Mass Spectrometry for Large Scale Quantitation

In this webinar, we will cover building high performance methods, generating a high quality spectral library and using it to reveal important expression changes in your pathway of interest, and even how to go back in time and use a DIA file’s record observable proteome to retrospectively interrogate data for new target peptides and proteins.

Extracts of a number of Allium species inhibit α-glucosidase, the enzyme responsible for glucose production in type 2 diabetes, and the principal active constituents have been identified by HPLC-MS-SPE-NMR. These species could be developed as functional foods or mined as sources of drugs to treat the disease.

An eco-friendly, rapid and inexpensive GC/MS method for the determination of acrylamide in cereal-based baby foods has been devised, optimising and minimising sample treatment processes.

This review examines the efficiency and reliability of available sample pre-treatment methods and their application in different fields of metabolomics and is in three sections dealing with pre-extraction techniques, the choice of extraction solvents, and a description of the most used extraction techniques.

The emphasis of this book is on understanding the principles and applications behind the main ideas in chemometrics, which can then be applied to a wide variety of problems in chemistry, chemical engineering and allied disciplines.

Factor analysis is a mathematical tool for examining a wide range of data sets, with applications especially important to the design of experiments (DOE), spectroscopy, chromatography, and chemometrics. In this free chapter from "Factor Analysis in Chemistry" Edmund Malinowski introduces the technique, declaring that "every problem has a solution"!

Paola Dugo and Peter Q. Tranchida discuss food analysis in general, as well as the modern techniques needed to overcome the current-day analytical challenges.
