1. 1. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography

   Master-uppsats, Lunds universitet/Kemiska institutionen

   Författare :Mohamad Abd Elwadood; [2023]
   Nyckelord :Analytical Chemistry; Fatty Acids; Gas Chromatography; Green Herbicides; Retention Index; Flame Ionization Detector; Mass Spectrometry; Supercritical Carbon Dioxide Extraction.; Chemistry;

   Sammanfattning : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. LÄS MER

3. 2. Geobacillus 7349 – A new potential biosurfactant producing microorganism

   Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Författare :Zhuoying Deng; [2023]
   Nyckelord :biosurfactant; rhamnolipids; HPLC; HPAEC-PAD; bacteria growth; downstream purification; liquid-liquid extraction; biotechnology; Chemistry;

   Sammanfattning : The main aim of this master project is to find out whether strain Geobacillus 7349 can produce biosurfactant during their growth by extraction and characterization of the product. The other goal is to optimize the cultivation condition of the strain. LÄS MER

4. 3. The initial steps in the pursuit to diagnose trimethylaminuria with liquid chromatography-tandem mass spectrometry and UniSpray ionization at CMMS

   Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

   Författare :Cristian Fransson; [2022]
   Nyckelord :;

   Sammanfattning : Trimethylaminuria is an autosomal recessive disorder characterized by a decreased oxidation capacity of trimethylamine to trimethylamine-N-oxide in the liver. The condition is diagnosed by estimating concentrations of trimethylamine and trimethylamine-N-oxide in human urine and then evaluating their respective creatinine ratios and the oxidation efficiency percentage.

5. 4. Fettsyror i öl : Kvalitativ analys av fettsyreprofiler ur bryggningsprocessen vid Åbro Bryggeri

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

   Författare :Mikael Subhi Aboode; [2022]
   Nyckelord :;

   Sammanfattning : Beer is a fermented alcoholic beverage that spans back to over 5000 years years ago and is consumed all over the world. Beer is usually made from malted barley but it can also be made from different cereals and starches. Beer contains both saturated and unsaturated fatty acids (FA) which are derived from the malt that is used. LÄS MER

7. 5. A study of the adsorption isotherms of Ion-pair reagents

   Kandidat-uppsats, Karlstads universitet

   Författare :Mehmet Bilici; [2022]
   Nyckelord :Tributylamine; adsorption isotherm; liquid-liquid extraction; gas chromatography;

   Sammanfattning : In this project, the optimization of obtaining adsorption isotherms for the ion pair reagent, tributylamine was tested. The goal was to have a better understanding of the chromatographic process when separating biomolecules, such as oligonucleotides. LÄS MER
