Stefano Pelagatti, Paolo Magni, Fausto Pigozzo
Purpose: We present a newly developed gas sampling valve module for the Thermo Scientific™ TRACE™ 1300 Series Gas Chromatograph (GC).
|GC-MS/MS ANALYSIS OF BENZODIAZEPINES USING ANALYTE PROTECTANTS|
Jeremy Matthews, Alex Chen, Flavio Bedini
Purpose: Assess the feasibility of using analyte protectants to improve the analysis of benzodiazepines.
|GC-MS/MS Analysis of Pesticide Residues in Green Tea Extracted by QuEChERS with Acetonitrile as Final Solvent|
Cojocariu C., Morgan P., Silcock P., Pelagatti S., Magni P. and Pigozzo F.
This poster describes the analysis of several challenging pesticides from green tea samples using GC-MS/MS and acetonitrile as final extraction solvent. The compounds analysed are representatives of various classes of pesticides, such as carboxamids, OC, OP, pyrethriods, aromatic, phenylamides.
|Exploring The Benefits Of Automated Unattended Sample Derivatization Prior To Gas Chromatography Analysis|
A. Caruso, M. Santoro, P. Magni, S. Pelagatti, R. Facchetti
Purpose: Exploring the possibility to perform the sample preparation steps necessary for the derivatization of analytes in a fully automated and reliable way by means of the same robotic sampler used for sample injection into the gas chromatograph.
Methods: As an example of application we screened dairy products for melamine and its derivates presence via GC-MS/MS.
Results: The outcome are good and precise results that show how it is possible to reliably automate sample preparation opera
|Determination of Veterinary Drug Residues in Milk by GC/MS and GC/ECD|
Yu Chongtian, Lv Jianxia
Purpose: Develop a rapid, sensitive method for determining amitraz and its metabolites in milk.
Methods: Samples were hydrolyzed in acidic condition and extracted with hexane. After derivativation, the samples were analyzed by GC-ECD or directly by GC-MS.
Results: The results show that GC-MS determination of amitraz and its metabolites is rapid and sensitive.
|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, Jonathan M. Sloan, Graeme Winter, Tobias S. Richter, NeXus International Advisory Committee, Committee on the Maintenance of the CIF Standard
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.
