  1. 6. Method development for quality control of the primary explosive, Potassium 4,6-Dinitrobenzofuroxan (KDNBF)

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Edvin Elmroth; [2020]
    Keywords : “Green” explosives; KDNBF; GC-FID; HPLC-UV VIS; Potentiometric titration;

    Abstract : “Green” explosives are an important sub-family of explosives due to the banning of explosives based on heavy metals, such as lead azide and lead styphnate, according to the REACH list. A substitute to lead azide is potassium 4,6-dinitrobenzofuroxane (KDNBF) which is an alternative “green” explosive. READ MORE

  3. 7. Catalytic hydrotreating of lignin

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Markus Lilja; [2019]
    Keywords : Lignin; hydrotreating; kemiteknik; chemical engineering; Chemistry; Technology and Engineering;

    Abstract : One of the main challenge’s society faces today is climate change caused by CO2 due to the de-pendence on fossil fuels. To combat the increasing CO2 levels there is a need to develop renewable fuels. One such fuel could potentially be derived from lignin. In this thesis, lignin derived from a pulp and paper mill was first treated and cleaned. READ MORE

  4. 8. Ethanol, ethyl glucuronide, and ethyl sulfate kinetics after multiple ethanol intakes : A study of ethanol consumption to better determine the latest intake of alcoholin hip flask defence cases

    University essay from Linköpings universitet/Kemi

    Author : Rickard Lundberg; [2018]
    Keywords : Ethanol; ethyl glucuronide; ethyl sulfate; kinetics; multiple intakes; hip flask defence; GC-FID; UPLC-MS MS;

    Abstract : The hip-flask defence is a common claim in drunkdrinking cases. In Sweden and Norway two different models are used to determinethese cases. In Sweden one blood and two urine samples taken 60 minutes apartare used for analysis. In Norway two blood samples taken 30 minutes apart areused. READ MORE

  5. 9. Analysis of short chain fatty acids in faecal samples : development and validation of a new method

    University essay from SLU/Dept. of Food Science

    Author : Nils Ewald; [2016]
    Keywords : short chain fatty acids; SCFA; faeces; dietary fibre; quantification; gas chromatography; flame ionization detector; GC-FID;

    Abstract : Short chain fatty acids (SCFA) are produced by the gut microflora following the intake of complex carbohydrates and have been suggested as a contributor for some of the health benefits associated with dietary fibre (DF) intake. For further research of the mechanisms and effects of SCFA, reliable and accurate methods for analysis of SCFA in different biological samples are needed. READ MORE

  6. 10. Techniques for Determining Alcohol Levels in Wine and Mulled Wine

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Camilla Brus; [2015]
    Keywords : ;

    Abstract : The aim of this study is to in cooperation with Grythyttan Vin compare and evaluate the accuracy and precision of the Alcolyzer Wine. The Alcolyzer Wine is a Near Infrared based instrument that was compared to GC-FID, GC-MS and distillation. Samples were taken from cisterns at Grythyttan Vin along with finished product samples.
