Automated, Rapid And Reliable Determination Of Dissolved Gases In Water By Static Headspace – Gas Chromatography
A. Caruso, M. Santoro, F. Bedini, P. Magni, S. Pelagatti

Purpose: Exploring the possibility to perform a quantitative determination of dissolved gases in water in a reliable and accurate way. Methods: The quantification of dissolved gases is performed by building a calibration curve spiking blank water samples with increasing quantities of saturated water followed by headspace sampling and GC/ FID analysis. Results: The results show good correlation factors and limit of quantification lower than 10ppb for the four gas analyzed.

Coping with BIG DATA Image Formats: Integration of CBF, NeXus and HDF5, A Progress Report
Herbert J. Bernstein,[1] Jonathan M. Sloan,[2] Graeme Winter,[2] Tobias S. Richter,[2] NeXus International Advisory Committee,[3] Committee on the Maintenance of the CIF Standard[4]

The best of CBF/imgCIF (the Crystallographic Binary File, which has a complete description of the experiment), NeXus (a common data framework for neutron, X-ray and muon science, which gracefully handles large data sets) and HDF5 (Hierarchical Data Format, version 5, the high-performance data format used by NeXus) are being combined for the management of BIG DATA at synchrotrons.

On-chip quantification of miRNA using digital droplet PCR
Q. Cai1, R.S. Wiederkehr1, B. Jones1, B. Majeed1, T. Stakenborg1, P. Fiorini1, L. Lagae1, M Tsukuda2, T. Matsuno2, I. Yamashita2

miRNAs have a great potential in diagnostics. Hence, automated profiling of miRNAs are of great interest. In-house technology show that it is possible to implement a multiplexing assay for miRNAs on a microfluidic chip using digital droplet PCR.

New LEGENDplex™ Multi-Analyte Flow Assay Panels for Simultaneous Quantification of 13 Th Cytokines in Human and Mouse Samples
Binggang Sun, Jingjing Yao, Jiaming Hu and Shaoquan Ji

We have developed two multiplexed assay panels, human and mouse, using fluorescence–encoded beads, suitable for use on various flow cytometers. Both panels allow simultaneous quantification of 13 human or mouse cytokines, including interleukins (IL-2, 4, 5, 6, 9, 10, 13, 17A, 17F, 21, 22), IFN-? and TNF-a. These Th cytokine panels can be used for serum, plasma, cell culture supernatant and other sample types, offering useful tools for biomedical research and drug discovery.

Discrimination of spectrally overlapping fluorochromes using Sony Corporation’s (SP6800) Spectral Analyzer
Divekar AA, Lee MJ, Kakuta M, Nitta N, Furuki M, Yang XF and Ransom JT

SP6800, a novel spectral analyzer from Sony Corporation, uses an innovative optics system that collects all emitted light and eliminates the need for band pass filters. Our data show that the SP6800 can perform all the analysis similar to a traditional cytometer with the added feature of separating spectrally overlapping fluorophores.

GC-MS Comparison of Lavindin Grosso Oil Obtained by Steam Distillation and SFE
Claudia Worley, Lisa Zona, Susan Sonchik Marine

Oil was extracted from Lavindin Grosso using steam distillation and using supercritical fluid extraction (SFE). Multiple analyses of the same extract demonstrated repeatability of the analytical method. The variability between batches of distillate bracketed the composition obtained by SFE. The differences among the oils could be attributed more to where the lavender was grown than to the extraction method.
