Silicone wristbands promoting charitable organizations and which are popular throughout the world as a fashion statement can be used to monitor exposure of individuals to contaminants in their local environment, according to a study published in the journal Environmental Science and Technology.1 The authors of the study propose silicone bands as passive samplers that can give a temporal and spatial picture of human contaminant exposure.
Incognito discusses the impending technological singularity of analytical chemistry. Is it time to take back control from the machine?
Scientists from the University of Florence in Italy have developed a novel fast ion chromatographic (FIC) method for the analysis of fluoride in Antarctic snow and ice. Data from fluoride analysis has the potential to assist scientists to build up a picture of past volcanic activity.

Gerard Rozing has been announced as the winner of the second annual Uwe D. Neue Award in Separation Science. The award was created by Waters Corporation (Massachusetts, USA) to recognize the work of distinguished industrial scientists, in honour of Dr Uwe D. Neue, late scientist and Waters Corporate Fellow. Rozing will receive the award at the upcoming 41st International Symposium on High Performance Liquid Phase Separations and Related Techniques (HPLC2014) held on 11–15 May in New Orleans, USA.
The United States woefully underfunds international collaborations with the Czech Republic. Yet, it is a country that produces excellent scientists who are distinctly passionate about science, and who have been educated to demonstrate not only a strong mastery of chemistry basics, but also superb knowledge of the integration of high-level mathematics and computer programming skills into their science. One need not look very far in the separation science and mass spectrometry (MS) fields in the United States to find eminent leaders with roots in the Czech Republic.

Scientists in Malaysia have developed a useful metabolomics approach that could aid analysts working in natural drug discovery. The team applied liquid chromatography–mass spectrometry (LC–MS) coupled with principle component analysis (PCA) to screen more than 4000 natural extracts for novel photosensitizer drugs.

LC–MS Deconstructs the "Poppy Seed Defense"
Gerstel GmbH & Co. KG (M?lheim an der Ruhr, Germany) and Spark Holland (Emmen, The Netherlands) have announced an original equipment manufacturer (OEM) agreement. The agreement will allow Gerstel to develop and market fully integrated automated dried blood spot (DBS) technology from Spark Holland that recently received a US patent.
Frederic Lynen discusses why LC–MS is the ideal analytical tool for the quantitative analysis of analytes in biological samples, and presents a new HILIC-based SPE approach to improve analyte recovery and sensitivity.

An efficient method for forensic analysis of amphetamines and synthetic cathinones - the illicit drugs often called "bathsalts" - in hair samples
The advent of ultrahigh-pressure liquid chromatography (UHPLC) and its successful commercialization in the last few years has brought forth a modern high performance liquid chromatography (HPLC) platform capable of higher speed, resolution, precision, and sensitivity. Currently, all major HPLC manufacturers have some type of low-dispersion UHPLC products with upper pressure limits ranging from 15,000 to 19,000 psi (1000 to 1300 bar) on the market. This installment describes a number of popular myths or half-truths in UHPLC and provides data that contradict or even repudiate some of these commonly held beliefs.
Daniel W. Armstrong, a professor of chemistry and biochemistry at the University of Texas Arlington in Arlington, Texas, is to receive the 2014 American Chemical Society Award in Separations Science and Technology.
In the pharmaceutical industry, the demonstration of drug substance (DS) or drug product (DP) stability over the shelf life is an important aspect of the regulatory requirements.
