LCGC and Spectroscopy, in conjunction with Pittcon, will be presenting LIVE video interviews at Pittcon 2011 in Atlanta, GA, on March 14 and 15. Interviews with leading researchers and industry experts will cover trends and applications in the fields of chromatography and spectroscopy. On March 16, join us for interactive CHROMacademy demonstrations and discussions.

Thermo Fisher Scientific has announced the initial findings of stroke research conducted by its Biomarker Research Initiatives in Mass Spectrometry (BRIMS) centre in collaboration with Massachusetts General Hospital (MGH), Harvard University. According to the company, the research provides potentially significant insight into patent foramen ovale (PFO) and its connection with strokes.

Thermo Fisher Scientific has launched a YouTube channel dedicated to chromatography videos. The first two videos uploaded provide educational information on the mechanics of GC and sample preparation.

Most plants used in traditional Chinese medicine must be processed before their medicinal usage; hence the effective ingredients may differ from those in the freshly harvested plant extracts. In this work, we present a fast and generic approach using sub-2-?m liquid chromatography–time-of-flight–mass spectrometry (sub-2-?m-LC–TOF-MS) coupled with multivariate statistical data analysis to systematically profile ingredient changes between fresh and processed samples of huang jing.

The inclusion of time-resolved selected reaction monitoring (SRM) functionalities into mass spectrometer control software allows large numbers of peptides to be quantified using short LC–MS-MS methods.

The metabolomics workflow described here combines untargeted (discovery) quadrupole time-of-flight (Q-TOF) liquid chromatography–mass spectrometry (LC–MS), targeted (confirmation) triple-quadrupole LC–MS-MS, and sophisticated data mining as an effective means to elucidate metabolite changes.

Increases in vitamin D testing frequency have required more rapid and cost-effective solutions for determining vitamin D levels in plasma. This LC–MS method was adapted for use with core-shell columns to achieve run times of less than 4 min.

PSS Application Note

There are many enjoyable aspects to my role here at LCGC. None rivals the pride, however, I feel in announcing the winners of the 2011 LCGC Lifetime Achievement and Emerging Leader in Chromatography Awards.

Fossilomics uses MS to extract amino acid sequence information from subpicomole quantities of protein and peptide fragments that remain in certain fossil samples. The sequences are compared to databases and validated with search statistics and high-confidence sequences. The validated sequences can then be used to place the fossils on the evolutionary tree.

Sample preparation is one of the most critical steps of the development and application of an analytical methodology.
