Liquid chromatography-inductively coupled plasma mass spectrometry.
The technique of coupling liquid chromatography to inductively plasma mass spectrometry (ICP-MS) is reviewed. A brief introduction to the ICP-MS instrument is given as well as methods to couple the two analytical instruments together. The various types of LC that have been used with ICP-MS detection are discussed and advantages over traditional methods of detection are highlighted, such as the ...
متن کاملSingle Particle Inductively Coupled Plasma Mass Spectrometry
Nanotechnology is an emerging and rapidly growing field whose dynamics and prospects pose many great challenges to scientists and engineers. Nanoparticles are being used in many materials and products, including coatings (on plastic, glass and clothing), sunscreen, antimicrobial bandages and clothing, MRI contrast agents, biomedical elemental tags and fuel additives, only to name few. However, ...
متن کاملLaser Ablation Inductively Coupled Plasma Mass Spectrometry
New analytical techniques for multiparametric characterisation of individual cells are likely to reveal important information about the heterogeneity of immunological responses at the single-cell level. In this proof-of-principle study, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was applied to the problem of concurrently detecting 24 lineage and activation markers e...
متن کاملImproved sweat test method for the diagnosis of cystic fibrosis.
We describe a new technique of collecting sweat for measurement of osmolality and sodium concentrations. Eighty two subjects were studied--39 controls and 43 patients with cystic fibrosis. Adequate amounts of sweat were obtained in 81 subjects and sweat was analysed for both osmolality and sodium concentrations in 73 subjects. The 34 controls gave sweat osmolality and sodium values ranging from...
