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.

Serum from hepatocellular carcinoma (HCC) patients, liver cirrhosis patients and healthy volunteers were analyzed using NMR and LC/MS to identify potential biomarkers with diagnostic and/or prognostic values for HCC.

Six of the preservatives known as parabens have been extracted from cosmetics by a new procedure combining ultrasonic nebulisation with dispersive liquid-liquid microextraction, using water in place of an organic solvent as the dispersant.

The emissions of carbonyl compounds linked to health and environmental problems from a ship diesel engine running on a heavy fuel oil are three-fold higher than those with a standard diesel fuel.

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.
