Journal Highlight: The effectiveness of multi-element fingerprints for identifying the geographical origin of wheat

Date: May 1, 2017

Author: spectroscopyNOW

The multi-elemental compositions of wheat have been analysed by high-resolution ICPMS with multiway analysis of variance to investigate the influences of region, genotype, harvest year and their interactions on all elements.

Pre-concentrated silver: FAAS analysis

Date: Apr 15, 2017

Author: David Bradley

Researchers in China have used a cloud point extraction (CPE) method to pre-concentrate trace levels of silver present in water samples for subsequent flame atomic absorption spectrometry (FAAS) analysis.

Journal Highlight: A New LA-ICP-MS Method for Ti in Quartz: Implications and Application to High Pressure Rutile-Quartz Veins from the Czech Erzgebirge

Date: Apr 3, 2017

Author: spectroscopyNOW

A new method has been proposed for determining 48Ti mass fractions in quartz by LA-ICP-MS at the 1 μg g−1 level, relevant to quartz in HP-LT terranes, using natural quartz as a reference material rather than NIST reference glasses.

FAAS testing one's metal: Steel analysis

Date: Feb 15, 2017

Author:

Researchers in Japan have used a new flame atomic absorption spectrometer system, comprising a bright xenon lamp as the primary radiation source and a high-resolution Echelle monochromator, to study several 3d transition metal elements known to potentially be present in steel.

Moody students? Zinc deficiency could be to blame

Date: Jan 15, 2017

Author: David Bradley

Zinc deficiency has been suggested as one possible risk factor for the onset and progression of mood disorders. A study utilising flame atomic absorption spectrometry (FAAS) has been carried out to assess this hypothesis in adolescent female high school students.
