A Novel Sample Preparation Method for Ultra-High Vacuum (UHV) Secondary Ion Mass Spectrometry (SIMS) Analyses

12-Jun-2018 | wanfeng zhang; Xiaoping XIA; Yanqiang Zhang; Touping Peng; Qing Yang, Journal of Analytical Atomic Spectrometry, 2018

Secondary ion mass spectrometry (SIMS) has been applied to analyze a wide range of material for earth science research due to its high sensitivity, high precision and capacity for in-situ micro-analyses. This technique operates under ultra-high vacuum (UHV) conditions, especially for water ...

Label-free, high-throughput detection of P. falciparum infection in sphered erythrocytes with digital holographic microscopy

01-Jun-2018 | Matthias Ugele; Markus Weniger; Maria Leidenberger; Yiwei Huang; Michael Bassler; Oliver Friedrich; Barbara Kappes; ..., Lab on a Chip, 2018

Effective malaria treatment requires rapid and accurate diagnosis of infecting species and actual parasitemia. Despite the recent success of rapid tests, the analysis of thick and thin blood smears remains the gold standard for routine malaria diagnosis in endemic areas. For non-endemic regions, ...

Concomitant desalting and concentration of neuropeptides on a donut-shaped surface pattern for MALDI mass spectrometry

24-May-2018 | Sook Yoon; Sanghwan Park; Min Sun Kim; Chang Young Lee, Chemical Communication, 2018

We demonstrate that a donut-shaped surface pattern consisting of a central hydrophobic region and a surrounding hydrophilic region simultaneously concentrates and desalts a solution of neuropeptides with a high salt content. Our approach greatly simplifies the sample preparation process for MALDI ...

Solid-phase extraction as sample preparation of water samples for cell-based and other in vitro bioassays

24-May-2018 | Peta A. Neale; Werner Brack; Selim Aït-Aïssa; Wibke Busch; Juliane Hollender; Martin Krauss; Emmanuelle Ma ..., Journal of Environmental Monitoring, 2018

In vitro bioassays are increasingly used for water quality monitoring. Surface water samples often need to be enriched to observe an effect and solid-phase extraction (SPE) is commonly applied for this purpose. The applied methods are typically optimised for the recovery of target chemicals and ...
