Heavy metals in your hibiscus: Infusion refusal

Date: May 15, 2013

Author: David Bradley

Inductively coupled plasma optical emission spectrometry (ICP-OES) and flame atomic absorption spectroscopy (FAAS) have been used to determine concentrations of metals in digests and infusions of Hibiscus sabdariffa (petals), Rosa canina (receptacles), Ginkgo biloba (leaves), Cymbopogon citratus (leaves), Aloe vera (leaves) and Panax ginseng (roots).

Acoustic archaeology: A sound approach

Date: May 15, 2013

Author: David Bradley

Researchers in the UK have carried out the most detailed analysis ever of the archaeological remains of the lost medieval town of Dunwich on England's Suffolk coast. The study analysed data obtained via acoustic spectroscopy to see the ruins through the murky depths of the North Sea.

Combined effort: Spectroscopic cancer clues under the microscope

Date: May 15, 2013

Author: David Bradley

A combination of atomic force microscopy (AFM) and nuclear magnetic resonance (NMR) spectroscopy could provide oncologists and cancer researchers with a new way to probe how cancer cells spread in the body through metastasis as well as other disease-related processes.

Journal Highlight: An evaluation of standardized software for processing GC/MS data from different vendors' instruments in a forensic laboratory

Date: May 13, 2013

Author: spectroscopyNOW

The data processing performance of a third-party processing software product has been compared with the software from three instrument vendors in casework analysis in a forensic environment.

Journal Highlight: X-ray fluorescence analysis of Co, Ni, Pd, Ag, and Au in the scrapped printed-circuit-board ash

Date: May 7, 2013

Author: spectroscopyNOW

A validated method for the measurement of Co, Ni, Pd, Ag, and Au in ash derived from scrapped printed circuit boards used X-ray fluorescence spectrometry and gave similar results to those from atomic absorption spectrometry.

Journal Highlight: Determination of the anti-viral drug Ribavirin in dosage forms via micelle-enhanced spectrofluorimetric method

Date: May 7, 2013

Author: spectroscopyNOW

A simple and sensitive spectrofluorimetric method was developed for the determination of Ribavirin in pharmaceutical formulations, based on its fluorescence spectral behaviour in a sodium dodecyl sulfate micellar system.

Journal Highlight: Mass spectrometry imaging under ambient conditions

Date: May 7, 2013

Author: spectroscopyNOW

Recent developments and applications of ambient ionization techniques for mass spectrometry imaging have been reviewed and the role of bioinformatics in acquiring and interpreting the chemical and spatial information is described.

Pork processing: Proteins influencing water holding capacity and drip loss

Date: May 1, 2013

Author: Steve Down

The proteome of fresh pork meat has been examined to locate proteins that are involved in the abnormal loss of water and soluble proteins due to limited water holding capacity, which impacts on meat quality.

Cocaine on currency: Higher levels associated with criminality

Date: May 1, 2013

Author: Steve Down

US scientists have analysed 17 years worth of data on the contamination of currency with cocaine to determine the levels which are statistically higher than background, so that banknotes contaminated by drug-related crime rather than general contamination during circulation can be identified.

Combined forces: AFM boosts IR

Date: May 1, 2013

Author: David Bradley

A technique that combines atomic force microscopy (AFM) with infrared spectroscopy has allowed researchers, for the first time, to study the infrared absorption of semiconductor plasmonic microparticles on the nanometre scale.
