Mass Spectrometry

In this month's "MS-The Practical Art," Michael Balogh takes a closer look at insight provided by Chuck McEwen regarding obstacles while using solvents.

Serum protein profiling using mass spectrometry (MS) is one of the most promising approaches for biomarker identification.

In Part I of this two-part look at spectral interpretation, Michael Balogh examined the ability to see and appreciate the product of our analytical devices. In Part II, he takes a closer look at the tools of the trade.

Despite their different levels of technological maturity, CE and LC coupled with electrospray ionization MS techniques can be operated at the same level of automation. However, they differ in their configuration, selectivity, sensitivity, and method development.

Current sample preparation procedures for LC–MS as applied to samples from biological matrices.
