    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multi element analysis; trace element; ICP-AES; inductively coupled plasma atomic emission spectromtery; water analysis; liver analysis; non digested samples; medical samples; biological samples; samples from biopsies and autopsies; mice organ; fast analysis; internal standard; preconcentration; matrix elimination; Cu; Zn; Mn; Co; Pb; Cd; Mg; Ca; Fe; Ni; Cr; S; P; K; Al; Analytical chemistry; Analytisk kemi; Analytical Chemistry; Analytisk kemi;

    Abstract : This thesis describes two different sample preparation strategies for inductively coupled plasma atomic emission spectrometry (ICP-AES), and their ability regarding multi element quantification in complex samples. Sensitivity, repeatability, reproducibility and accuracy were investigated. READ MORE

  4. 2. Inductively Coupled Plasma Spectrometry for Speciation Analysis : Development and Applications

    Author : Niklas Forsgard; Jean Pettersson; Marit Andersson; Jonas Bergquist; Walter Lund; Uppsala universitet; []
    Keywords : Analytical chemistry; Speciation analysis; Atomic emission spectrometry AES ; Mass spectrometry MS ; Inductively coupled plasma ICP ; Liquid Chromatography LC ; on-line sample pre-treatment; Organic phosphour; Siderophores; Slurry nebulization; matrix effects; Analytisk kemi;

    Abstract : In analytical chemistry the main goal is normally to determine the identity and/or concentration of one or more species in a sample. The samples analyzed are often natural samples, containing numerous different species in a complex matrix and the choice of technique for multi-elemental detection is in general inductively coupled plasma spectrometry.

    Abstract : Inductively coupled plasma mass spectrometry (ICP-MS) is in focus in this thesis. Fundamental studies of ICP double focusing magnetic sector MS are presented, and some possible applications are discussed. READ MORE

  6. 4. Lead in blood. ICP-MS studies of lead in plasma, blood and erythrocyte proteins

    Author : Ingvar A Bergdahl; Avdelningen för arbets- och miljömedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; distribution; plasma; blood; erythrocytes; lead-binding prtoeins; delta-aminlevulinic acid dehydratase; inductively coupled plasma mass spectrometry; ALAD; arbetsmiljömedicin; Occupational health; industrial medicine; Lead; toxicity; ICP-MS; Yrkesmedicin;

    Abstract : An inductively coupled plasma mass spectrometry (ICP-MS) method for the determination of lead in blood plasma has been developed. The detection limit was below 0.1 microgram/liter, and the precision 5%. There was no significant difference between levels in plasma and serum. READ MORE

  7. 5. Isotope Ratio and Trace Element Measurements Using Inductively Coupled Plasma – Mass Spectrometry : Method Development and Applications in Environmental Forensics

    Author : Simon Pontér; Anders Widerlund; Hjalmar Laudon; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Isotope ratio measurements; screening analysis; ICP-MS; MC-ICP-MC; multi-tracer studies; fractionation; Environmental Forensics; Tracing; Tillämpad geokemi; Applied Geochemistry;

    Abstract : Environmental Forensics is a scientific methodology developed for identifying sources, the timing of release, and transport pathways for potentially hazardous environmental contaminants. It combines a variety of analytical methods with principles derived from disciplines such as chemistry, geology, geochemistry, hydrogeology, and statistics, with the purpose to provide objective scientific and legal conclusions on the source and/or time of a contaminant release.
