XRF and Isotope MS for Evaluating Ancient Coins

Elemental and isotope analysis of the metals in ancient artefacts such as the prutah shown here sometimes can pinpoint the places where the metal was mined.Elemental and isotope analysis of the metals in ancient artefacts such as the prutah shown here sometimes can pinpoint the places where the metal was mined.Elemental and isotope analysis of the metals in ancient artefacts such as the prutah shown here sometimes can pinpoint the places where the metal was mined. This can be combined with historical sources to determine when the coin was likely struck. Archaeologists can use the evidence to identify or narrow date ranges of historical significance.

Breath testing for drugs with LC-MS/MS

Olof Beck Photo: Ulf SirbornA new study from the Swedish medical university Karolinska Institutet presents a technique using LC-MS/MS that makes drug testing possible through exhaled air for the first time. By examining people who had received emergency care for an amphetamine overdose, the researchers found that in all cases there were traces of amphetamine and metamphetamine in the exhaled breath.

Raman microscopy distinguishes fertile and infertile human sperm cells

Scientists from Ruhr-Universität Bochum have used Raman micro-spectroscopy to distinguish, within seconds, healthy fertile and infertile sperm cells. The method has the potential for a novel fertility technology and a test scheme which does not only rely on morphological characteristics, but also utilises chemical signatures.

MS method could stop shark oil being used in cosmetics and vaccines

SharkCoupling an isotope ratio mass spectrometer to an elemental analyser or gas chromatograph/combustion system has been used to analyse squalene and squalane, oils often used in the production of cosmetics and vaccines, and can show whether they came originally from the liver oil of deepwater sharks or from olive oil.

Synchrotron imaging of single starch granules

David Wetzel and Yong-Cheng Shi of Kansas State University, USA, and John Reffner from John Jay College, City University of New York, USA have applied microscopic chemical imaging to single modified starch granules. Starch manufacturers can use this to determine if the modifying agent used in the production process is uniformly distributed across individual modified starch granules. Mark Boatwright, a K-State graduate research assistant in grain science and industry assisted with data processing for the study.
