Analytical chemistry methods development

Analytical customization for specific target applications: Stefan Reimann (Empa Dübendorf) showed for the first time worldwide measurements of hydrofluoro alkenes at Jungfraujoch, using a proprietary preconcentration method and GC-MS.The analysis of industry-released organic compounds, e.g. the CFCs known to affect the ozone layer, is a scientific task with major societal impact.The optimization of the measurement technology and the embedment in a large network is essential to monitor the geographic and temporal evolution.Frank Dieterle (Novartis Basel) gave a practical demonstration of a customized analytical unit, the size of a small PC, for personalized healthcare, now available for private households.Its efficient and task-tailored functionality provides complex medical screening at the patient's fingertip.Similarly, the talk by Yingdi Zhu (EPFL Va lais) showed a quick diagnostic tool for bloodstream infection based on immunoaffinity MS.Sophie Bravo-Veyrat (University of Geneva) presented a high-throughput differential mobility spectrometry-MS method for blood stability check in transfusion bags, and Debora Käser (ETH Zurich) compared femtosecond versus nanosecond UV pulses for the laser ablation ICP-MS analysis of geological samples.'Smart compact models' validated to make 'complex analy tical cases'labaddressable: For instance, banana skin spots were investigated as a model for a (pre-clinical) study of melanomas Hubert Girault (EPFL Va lais).Rolf Kipfer (Eawag Dübendorf) showed noble gas analyses from Black Smokers in the Gulf of California, which support the hypothesis that the Paleocenic-Eocenic-Thermal maximum 55 million years ago was caused by magmatism and Black Smoker activity in response to the formation of the Atlantic Ocean.Carla Rigling (ETH Zurich) questioned the oversimplifying assumption that a single dominant molecular conformation in solution can represent all the experimental NMR data, whereas molecules are constantly subjected to conformational changes, which may indeed lead to misinterpretation of data: results on peptides exhibiting antimicrobial activity were shown.Myriam Guillevic (METAS Bern) showed a four-step method to produce smart reference gas mixtures for the complex analysis of fluorinated gases in a SItraceable way.The 18 oral presentations and 19 posters attracted full audiences all day long, creating the conditions for a fertile interanalytical forum.Based on this success, the CHanalysis will now move from the current 18-month interval to an annual meeting, with the next one taking place in spring 2018 in Beatenberg.
