Nitrile rubber materials were studied using flash analytical pyrolysis-GC–MS to demonstrate that this technique is a good tool to identify the additives in nitrile rubber.

A brief historical overview of DMS, followed by a synopsis of the instrumentation, physics, and chemistry behind the separation principles

DIP–MS is a fast and easy tool that can identify classes of compounds in opportunity crudes (heavy and ultraheavy crude oils, asphaltenes, and tar sands) in the field, without prior separation or treatment. It may enable fast screening of real samples to make a rough evaluation of the potential of reservoirs and oil fields.

A discovery-based, untargeted metabolomics analysis of hundreds of yeast metabolites under robust, controlled extraction conditions followed by identification is described.

The main limitations of quantification using MALDI imaging are discussed and the different approaches used for quantitative measurement in MSI are evaluated.

Crop development to improve yield or disease resistance has been explored for centuries and the technologies to measure these improvements have subsequently become complex.
