A flight of fancy: Electron pair emissions

Date: Feb 15, 2014

Author: David Bradley

Measuring electron pair emission is an experimentally difficult task, not least because it requires access to a synchrotron light source. Now, researchers have developed a new way to measure the emission of electron pairs directly by using a unique combination of a new laboratory light source with time-of-flight spectrometry.

Journal Highlight: Element fractionation analysis for infant formula and food additives by ICP-OES

Date: Feb 3, 2014

Author: spectroscopyNOW

A sequential separation procedure has been applied for the protein, lipid and serum fractions of infant formula, coffee cream, milk powder, whey powder and rice flour before analysis for essential and nonessential elements by ICP-OES.

Iron and age: Brain analysis

Date: Jan 15, 2014

Author: David Bradley

Graphite furnace atomic absorption spectrometry after microwave-assisted acid digestion of post mortem brain samples has investigated levels and distribution of iron. The work may ultimately offer new insights into the role of the trace metal in neurodegenerative diseases.

Oiling up: LIBS spots the Swan

Date: Dec 15, 2013

Author: David Bradley

LIBS has been used to analyse organic liquid media, such as vegetable oils and to highlight the "Swan band" of C2 emitted  aturated fatty acids, thus providing a single parameter for characterising this important food ingredient.

Journal Highlight: Investigation of long-term geochemical variations and magmatic processes at Mount St. Helens

Date: Dec 2, 2013

Author: spectroscopyNOW

The early magmatic history of Mount St. Helens has been constrained based on chemical zonation of phenocrysts from the different eruptive units and compositions of melt inclusions determined by LA-ICPMS.

Heavy metal: Not so fishy

Date: Nov 15, 2013

Author: David Bradley

There is ongoing concern regarding levels of heavy metal contamination of edible fish. However, a study of Atlantic species by a team in Morocco using atomic absorption spectroscopy shows that although cadmium, lead and mercury are present, concentrations are well below the safety thresholds published by the European Union.

Journal Highlight: SPE of lead and copper on a polyhydroxybutyrate-b-polydimethyl siloxane block copolymer disc and FAAS determination of them in water and food samples

Date: Nov 4, 2013

Author: spectroscopyNOW

Cu(II) and Pb(II) were extracted from food and water by SPE as their Sudan III chelates on a block copolymer disc for determination by flame atomic absorption spectrometry.

Laser fluorescence: It's a gas

Date: Oct 15, 2013

Author: David Bradley

Using what they refer to as off-the-shelf, US researchers have developed a laser fluorescence spectroscopic technique to measure how and when nanocrystals adsorb and release hydrogen or other gases. The new investigative approach could be useful in research into lower-cost catalytic converters for vehicle exhausts, the future development of fuel cell technologies and improved gas sensors for industrial and anti-terrorism applications.

Journal Highlight: Challenges in the analysis of heterogeneous pottery by LA–ICP–MS: A comparison with INAA

Date: Sep 30, 2013

Author: spectroscopyNOW

A pilot study assessing the use of LA–ICP–MS to analyse the clay matrix in pottery revealed the challenges of the technique for highly heterogeneous materials.
