  1. 1. Automation, hyphenation and multidimensional chromatography for PAH analysis : Analytical techniques to simplify sample complexity

    Författare :Hwanmi Lim; Roger Westerholm; Christoffer Bergvall; Stephen Wise; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; polycyclic aromatic hydrocarbon; PAH; benzo[a]pyrene; B[a]P; carcinogenicity; cancer risk assessment; complex matrix; automation; hyphenation; multidimensional chromatography; two-dimensional; method translation; online fractionation; benz[j]aceanthrylene; B[j]A; relative potency factor; Analytical Chemistry; analytisk kemi;

    Sammanfattning : One group of organic environmental pollutants which are potentially hazardous to human health is polycyclic aromatic hydrocarbons (PAHs). These compounds consist of two or more benzene rings in their structure among which benzo[a]pyrene (B[a]P) is classified as a human carcinogen. LÄS MER

  2. 2. Zur Getrennt‑, Zusammen‑ und Bindestrichschreibung von Substantivkomposita im Deutschen (1550–1710)

    Författare :Daniel Solling; Bo Andersson; Bettina Jobin; Claudine Moulin; Uppsala universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; open compound nouns; closed compound nouns; hyphenation; compound nouns; Early New High German; historical graphematics; historical graphemics; orthography; Getrenntschreibung; Zusammenschreibung; Bindestrichschreibung; Substantivkomposita; Frühneuhochdeutsch; historische Graphematik; historische Graphemik; Orthographie; German; Tyska;

    Sammanfattning : This thesis investigates the changes in whether compound nouns were closed (written as one word), open (written as separate words) or hyphenated in Early New High German between 1550 and 1710. Due to the fact that there were no orthographic norms in the German of this time, graphematic phenomena in this period of the German language are very fruitful to examine. LÄS MER

  3. 3. Enzymatic hydrolysis coupled to hot water extraction for determination of flavonoids in plants

    Författare :Sofia Lindahl; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; extraction; flavonoids; quercetin; biocatalysis; beta-glucosidase; sustainable chemistry; hyphenation; molecularly imprinted polymers; onion;

    Sammanfattning : The word sustainability is more and more frequently used within the field of chemistry and in many other fields. Green or sustainable chemistry was introduced during the 90 ́s as a field of chemistry where the environmental and health impacts of processes and products are evaluated and improved. LÄS MER

  4. 4. Advances in analytical methodologies for studies of the platinum metallome in malignant cells exposed to cisplatin

    Författare :Yvonne Nygren; Erik Björn; Knut Irgum; Bente Gammelgaard; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Method development; Metallome; Inductively coupled plasma mass spectrometry; Electrospray ionization mass spectrometry; Liquid chromatography; Hyphenation; Organic modifier; Cisplatin; Platinum; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : The scientific progress about the important chemotherapeutic drug substance cisplatin (CDDP) and its function has often been rendered by data difficult to interpret, and still many questions about its mode of action remains to be clarified by the scientific community. However, studies of CDDP possess a high complexity due to; i) low intracellular concentration, ii) many potential biomolecule targets, iii) poor or unknown stability of the intact drug and its biomolecule adducts and iv) complex and varying sample matrices.

  5. 5. Novel on-line mid infrared detection strategies in capillary electrophoretic systems

    Författare :Malin Kölhed; Bo Karlberg; Sven P. Jacobsson; Andre' J. Sommer; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; on-line hyphenation; mid infrared detection; capillary electrophoresis; FTIR; quantum cascade laser; aqueous samples; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Infrared absorption spectra can provide analytically useful information on a large variety of compounds, ranging from small ions to large biological molecules. In fact, all analytes that possess a dipole moment that changes during vibration are infrared-active. The infrared (IR) spectrum can be subdivided into far-, mid- and near- regions. LÄS MER
