Makarov A, Scigelova M. J Chromatogr A. 2010 Jun 18;1217(25):3938-45. The Orbitrap mass analyzer has become a mainstream mass spectrometry technique. In addition to providing a brief introduction to the Orbitrap technology and its continuing development, this article reviews the most recent publications quoting the use of the Orbitrap detection for a variety of chromatographic separation techniques. Its coupling to reversed-phase liquid chromatography (LC) represents undoubtedly the most ubiquitous approach to both small molecule and proteomic analyses. Multi-dimensional LC separations have an important role to play in the proteomics applications while an ultra-high-pressure LC is more frequently encountered in the area of metabolomics and metabolite analysis. Recently, special chromatographic techniques such as hydrophilic interaction chromatography and its variations have also been also cited with the Orbitrap detection.
