A New Frontier: NanoLC–NanoESI–MS in Astrobiology
March 20th 2014Mike Callahan, an analytical chemist at NASA's Goddard Space Flight Center (Maryland, USA), led a team to develop a new nano LC–nano ESI–MS method to detect life's building blocks in "spacedust". Callahan spoke to The Column about the inspiration behind the project, the challenges of analyzing extraterrestrial material in the laboratory, and future directions.
Novel Passive Sampling Using Silicone Wristbands
March 20th 2014Silicone 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.
Fluoride Analysis of Ice Cores Using Fast Ion Chromatography
March 20th 2014Scientists 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.
