  2. 11. Novel Solid Phase Extraction and Mass Spectrometry Approaches to Multicomponent Analyses in Complex Matrices

    Author : Nahid Amini; Gunnar Thorsén; Tuulia Hyötyläinen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sample preparation; SPE; RAM; GCB µ-trap; GCB disk; High temperature LC; LC MS; ESI; APCI; Matrix effects; LIT-MS; SALDI; Sample screening; Oxidized GCB; Silicon nitride; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Analysis of compounds present in complex matrices is always a challenge, which can be partly overcome by applying various sample preparation techniques prior to detection. Ideally, the extraction techniques should be as selective as possible, to minimize the concentration of interfering substances. READ MORE

  4. 12. Integrative Approaches in Shotgun Proteomics : From sample preparation to multifaceted data analysis

    Author : Mariya Nezhyva; Erik T. Jansson; Per Andrén; Gustaf Christoffersson; Jesper Velgaard Olsen; Uppsala universitet; []
    Keywords : bottom-up proteomics; thermal proteome profiling; mass-spectrometry imaging; data analysis; melanocortin receptor; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : Bottom-up proteomics mass-spectrometry gives an opportunity to shed light on var-ious biological aspects/characteristics such as protein composition, its modifications,interactions, and dynamics. Its applications span a wide range of biological sciencesaiming to eventually answer fundamental disease related questions or evaluate drugperformance and predict adverse effects. READ MORE

  5. 13. A Novel Miniaturised Dynamic Hollow-Fibre Liquid-Phase Micro-Extraction Method for Xenobiotics in Human Plasma Samples

    Author : Helena Hansson; Ulrika Nilsson; Bo Karlberg; Peter Haglund; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sample clean-up; human blood plasma; hollow-fibre liquid phase microextraction; supported liquid membrane extraction; SLM; HF-LPME; sample preparation; bioanalysis; liquid-liquid extraction; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Bioanalytical chemistry is a challenging field, often involving complex samples, such as blood, plasma, serum or urine. In many applications, sample cleanup is the most demanding and time-consuming step. READ MORE

  6. 14. New Techniques for Sample Preparation in Analytical Chemistry

    Author : Zeki Altun; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Kemi; Chemistry;

    Abstract : Sample preparation is often a bottleneck in systems for chemical analysis. The aim of this work was to investigate and develop new techniques to address some of the shortcomings of current sample preparation methods. READ MORE

  7. 15. Microfluidic blood sample preparation for rapid sepsis diagnostics

    Author : Jonas Hansson; Hjalmar Brismar; Aman Russom; Fredrik Nikolajeff; KTH; []
    Keywords : 3D fluidic networks; bacteria isolation; inertial microfluidics; lab-on-chip; microfluidics; particle filtration; PDMS membrane; selective cell lysis. sepsis;

    Abstract : Sepsis, commonly referred to as blood poisoning, is a serious medical condition characterized by a whole-body inflammatory state caused by microbial infection. Rapid treatment is crucial, however, traditional culture-based diagnostics usually takes 2-5 days. READ MORE
