Answering Life's Questions with Spectroscopy

Date: Jun 28, 2017

Author: Jon Evans

Spectroscopy has been a common analytical technique in laboratories for many years. Recently, however, it has begun to emerge from the laboratory, both figuratively and literally, as more and more researchers discover that it is ideally placed to answer the questions they want to ask.

Understanding diabetes: Atomic absorption spectrometry assists

Date: Jun 15, 2017

Author: David Bradley

Type 1 diabetes is a major cause of debilitation and premature death. Treating the disorder is complicated and costly. Now, a team in Brazil is using atomic absorption spectrometry and other techniques to look for potential metallic biomarkers for copper, magnesium, selenium, and zinc to correlate their concentrations with the patient metalloproteome.

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.
