  3. 12. The effect of temperature on the chemical stability of Vitamin C in a cosmetic product – Development of an HPLC-method for quantitative analysis

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Sofia Thuresson; [2022]
    Keywords : Vitamin C; HPLC; Stability; Degradation; Antioxidant; Vitamin C; HPLC; Stabilitet; Nedbrytning; Antioxidant;

    Abstract : Vitamin C är en populär ingrediens i hudvårdsprodukter, bland annat på grund av dess positiva effekter på kollagen-produktionen i huden och dess antioxidativa egenskaper. Dessvärre är vitamin C en känslig ingrediens som lätt bryts ned av ljus, syre, hög temperatur eller fel pH-värde. READ MORE

  4. 13. Evaluation of non-stationary signal processing methods for binary EEG classification

    University essay from Lunds universitet/Matematisk statistik

    Author : Amanda Ledell; [2022]
    Keywords : Mathematics and Statistics;

    Abstract : Electroencephalogram (EEG) measurements are notoriously noisy and non-stationary and there are several specialized techniques for their analysis and interpretation. In this thesis, we implement a collection of stationary and non-stationary methods including coherence, Phase Locking Value (PLV), Phase Lag Index (PLI), and their imaginary counterparts. READ MORE

  5. 14. Modeling and simulation of chromatographic separation in Modelon Impact

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Oliver Thelander; [2022]
    Keywords : Chemical engineering; Simulering; Modellering; Kromatografi; Adsorption; Modelica; Modelon Impact; Recirkulation; Simulation; Modeling; Chromatography; Recirculation; Technology and Engineering;

    Abstract : The aim of this master thesis is to implement a previously modeled chromatographic adsorp-tion process from MatLab into the Modelon Impact, a simulation software. Modelon Impact is using Modelica as language syntax that is useful for creating a large system of interconnected models that has the potential to work in different configurations. READ MORE

  6. 15. Development and validation of sample clean-up using solid phase extraction prior oil spill fingerprinting

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

    Author : Cheryl Loorents; [2022]
    Keywords : Oil spill; chemical fingerprint; solid phase extraction SPE ; development; validation.;

    Abstract : In a forensic investigation involving oil, a comparative analysis named oil spill fingerprinting between a source and an oil spill is normally performed. It is based on detecting a certain selection of biomarkers with gas chromatography (GC) coupled to mass spectrometry (MS) which are later divided into diagnostic ratios (DRs). READ MORE
