|Hyphenated Techniques as Modern Detection Systems in Ion Chromatography|
K.M. Ruth, A. Wille, S. Czyborra and J. Kleimann
Historically ion chromatography (IC) using conductivity detection has been successfully used for the analysis of ionic (e.g., anions and cations) and polar substances (e.g., organic acids or sugars). However, due to current toxicity concerns, analyses in complex matrices require improved sensitivities and selectivities.
|Stable Isotope Dilution Analysis of Organic Pollutants Using LC-MS/MS (QqQ) and Isotope Pattern Deconvolution|
A. Castillo, E. Gracia-Lor, A.F. Roig-Navarro, P. Rodriguez-Gonzalez, J.V. Sancho and J.I. García Alonso
LC-MS/MS equipped with a triple quadrupole (QqQ) in the Selected Reaction Monitoring (SRM) has been widely accepted as the main tool in the identification, structural characterization and quantitative determination of semi-polar and polar organic pollutants in food and environmental samples. However there are limitations with these techniques.
|Proton-Transfer Reaction Time of Flight Mass-Spectrometry (PTR-TOF-MS): Comparison of Compact-Time of Flight (C TOF) and High Resolution-Time of Flight (HRS TOF) Platforms|
A. Jordan, G. Hanel, E. Hartungen, P. Sulzer, H. Seehauser, S. Haidacher, R. Schottkowsky, F. Petersson, C. Lindinger, L. Mark and T. D. Mark
This poster outlines the latest developments in PTR-TOFMS technology which exceed previously reported TOF setups in terms of sensitivity, detection limits and fast response time.
|Novel Developments in Proton-Transfer-Reaction Mass-Spectrometry (PTR-MS): Switchable Reagent Ions (PTR+SRI-MS) and ppqv Detection Limit|
A. Jordan, G. Hanel, E. Hartungen, P. Sulzer, H. Seehauser, S. Haidacher, R. Schottkowsky, C. Lindinger, L. Mark and T. D. Mark
Proton Transfer Reaction - Mass Spectrometry (PTR-MS) is a well established technique for real-time trace gas analysis. This poster reports the latest developments in this field.
|Development of a Lab-on-a-Chip for the Characterization of Human Cells |
Richter, L., Stepper, C., Mak, A., Brückl, H. and Ertl, P.
Cell chips are developed to continuously monitor mammalian cell population dynamics in a non-invasive manner. In the presented work we describe the design, fabrication and characterization of a lab-on-a-chip for quantitative cell analysis.
|Label-free Identification of Microorganisms using a Contact-less Dielectric Microsensor|
Ertl, P., Richter, L., Reinthaler, A., Stepper, C., Mak, A., Kast, M., Heer, R. and Brückl, H.
Microfabricated biochips are developed to continuously monitor cell population dynamics in a non-invasive manner. In the presented work we describe the novel combination of contact-less dielectric microsensors and microfluidics to promote biofilm formation for quantitative cell analysis.
