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

Detailed study results challenge common beliefs about the mechanisms behind the excellent performance of core–shell particles.

In both East and West, new ideas have often met resistance.

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.

Many tools gas chromatographers keep on hand are specialized, but others can be found in the toolkits of plumbers and carpenters.

In a well-behaved method, changes in peak shape should occur gradually over hundreds or thousands of samples. Tailing of one or a few peaks usually points to a problem.

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

Gradients can provide improved peak shape, higher efficiency, and sometimes altered selectivity and improved resolution.
