Going Beyond the Surface: Analytical Application of LIBS

Laser Induced Breakdown Spectroscopy has many unique attributes that simplify elemental analysis of materials. A chief advantage is eliminating time-consuming and destructive sample preparation steps required in most other bulk analysis methods. In this webinar we  cover, amongst other things. the fundamentals of LIBS instrumentation and sampling and analyzing surface layers and coatings.

An international collaboration has developed a technique for creating quantum dots with identical, deterministic sizes as revealed by scanning tunnelling microscopy. The research could allow quantum dot architectures to be constructed with complete control allowing technologists to develop new nanophotonics and quantum information processing systems as well as enabling various fundamental scientific studies.

Six trace metals (Cd, Pb, Cr, Cu, Zn, and Mn) were analyzed in 43 representative tea products (18 green, 12 Oolong, and 13 black teas) from 7 main tea production provinces in China, using atomic absorption spectrophotometer, while two perfluorinated compounds were measured by HPLC-MS/MS.

I like coffee: I like teeth

Atomic absorption spectroscopy has been used in a new study to analyse changing concentrations of calcium in tooth enamel as it responds to the antibacterial effects of strong coffee on oral microbes. The research suggests that while coffee may well be the downfall of those who wish to have a shiny, white smile, it could at least prevent coffee drinkers from losing their stained teeth.

While even the best analytical techniques cannot rectify problems generated by sloppy sample preparation, this less "sexy" step between the point at which analytes are transferred from the sample matrix to a form suitable for analysis is often overlooked. Read a free chapter from "Sample Preparation Techniques in Analytical Chemistry " here.

See how you can determine the emission spectra of hydrogen and other elements with a diffraction grating, a meterstick, and a little trigonometry.

Professor Tony Mallet of the University of Greenwich presents an essay on elemental compositions from 'accurate mass' determinations.
