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

   University essay from Lunds universitet/Kemiska institutionen

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

   Abstract : 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. READ MORE

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

   University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

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

   Abstract : 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. READ MORE

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

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Cristian Fransson; [2022]
   Keywords : ;

   Abstract : 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. A study of the adsorption isotherms of Ion-pair reagents

   University essay from Karlstads universitet

   Author : Mehmet Bilici; [2022]
   Keywords : Tributylamine; adsorption isotherm; liquid-liquid extraction; gas chromatography;

   Abstract : 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. READ MORE

6. 5. Evaluation of Pre-Analytical Processes on Lipemic Whole Blood Samples Used in Forensic Toxicology

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Emily Elenstål; [2022]
   Keywords : lipemia; post-mortal; whole blood; benzodiazepines; Intralipid; liquid-liquid extraction; solid-phase extraction;

   Abstract : Introduction: Post-mortem whole blood samples differ greatly in quality, lipemia is one cause of concern in toxicological analyses. Around 4 % of all samples sent to RMV are given a notation of lipemic content. READ MORE
