  1. 1. Chemometric tools for enhanced performance in liquid chromatography-mass spectrometry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Dan Bylund; Mittuniversitetet.; Uppsala universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; MATHEMATICS; MATEMATIK; chemometrics; liquid chromatography; mass spectrometry; Analytical Chemistry; analytisk kemi;

    Abstract : Liquid chromatography-mass spectrometry (LC-MS) has become an important analytical on-line technique, capable of producing large amounts of data with high selectivity and sensitivity. Optimal use of the sophisticated instrumentation can be attained if the analytical chemists are guided to perform the proper experiments and to extract the useful information from the acquired data.

    Abstract : Liquid chromatography – mass spectrometry (LC-MS) methods were developed for the analysis of positron emission tomography (PET) radiotracers in biological matrices. Additionally, radiotracer chemistry was explored as an analytical tool for supporting LC-MS method development and imaging molecular interactions in miniaturised chemical analysis systems. READ MORE

  3. 3. Efficient algorithms for highly automated evaluation of liquid chromatography - mass spectrometry data

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Mattias Fredriksson; Mittuniversitetet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Digital filtering; Liquid chromatography; Mass spectrometry; Method; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : Liquid chromatography coupled to mass spectrometry (LC?MS) has due to its superiorresolving capabilities become one of the most common analytical instruments fordetermining the constituents in an unknown sample. Each type of sample requires a specificset?up of the instrument parameters, a procedure referred to as method development. READ MORE

  4. 4. Liquid chromatography : Mass spectrometry study of two biochemical alcohol markers

    University dissertation from Stockholm : Karolinska Institutet, Department of Medicine

    Author : Niclas Nikolai Stephanson; Karolinska Institutet.; Karolinska Institutet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The interest in biochemical alcohol markers for detecting acute and chronic alcohol consumption has expanded greatly during recent years. The development and application of laboratory tests identifying early problematic drinking and monitoring abstinence have the potential of reducing the healthcare costs and suffering associated with alcohol misuse.

  5. 5. Liquid chromatography-mass spectrometry in the analysis of radiolabelled compounds for positron emission tomography

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Benita Hyllbrant Forngren; Uppsala universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Methods for liquid chromatography-mass spectrometry (LC/MS) with electrospray ionization (ESI) have been developed for the determination of specific radioactivity and for metabolic studies of radiolabelled compounds used in positron emission tomography (PET). These compounds often provide an analytical challenge mainly due to their low concentrations in complex sample matrices. READ MORE
