Overall FID sensitivity depends upon the combustion gas flow-rates, the carrier-gas flow-rate, the flame jet exit diameter, the relative positions of jet and collector and, to a lesser degree, the detector temperature.
Is it possible to combine a serious scientific meeting together with social events and fun? Well if it is possible then the ExTech and HTC-9 meeting held in York, UK between 6?10 February came very close.
Biologists entering liquid chromatography?mass spectrometry (LC?MS) from a background of general LC rarely use their mass spectrometer to its full potential. Isotope peaks offer huge possibilities both in semi-quantitative interpretation of structure and in quantitative labelling studies. This article examines charge state, "easy" isotopes, such as chlorine, the slightly harder problem of sulphur compounds, and finally looks at a method for improved measurement of heavy labels in a metabolic study.
Sony has released details of its new e-book reader using E-Ink technology. This could transform the electronic reading experience. The lightweight reader could bring a whole new meaning to "book smart".
The department of Chemistry and Chemical Biology at Harvard University has purchased a site licence of the ACD/2D NMR processor. The Advanced Chemistry Development (ACD/Labs) processor will be deployed to all faculty staff and students for use on department-owned or leased computers as well as personal PCs.
