  1. 21. Development of a Method for Separation of Adenine Nucleotides

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Erika Miegel; [2020]
    Keywords : analytical chemistry; HPLC; HILIC; chromatography; technical analytical chemistry; teknisk analytisk kemi; Chemistry; Technology and Engineering;

    Abstract : Adenosine tetraphosphate, or Ap4A, is a nucleotide with very interesting proposed biological effects. Previous studies have indicated that blood glucose levels in mammals might increase in the presence of Ap4A, and that Ap4A might antagonize pancreatic ATP channels. READ MORE

  3. 22. 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

  4. 23. Autonomous Buffer Preparation

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Lukas Önnestam; [2020]
    Keywords : Buffer; Python; Automation; pH; Chemical engineering; Kemiteknik; Technology and Engineering;

    Abstract : Every laboratory involved with liquid chromatography (LC) has to solve the issue of a supply of mobile phase. In the case of reversed-phase liquid chromatography the mobile phase is polar in nature and most commonly aqueous solutions. With a source of distilled water in-house the possibility of creating a mobile phase supply is within reach. READ MORE

  5. 24. Identification of Trypsin Digested Transferrin using HPLC and MALDI-MS

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Weyni Ghebreamlak; [2019]
    Keywords : Transferrin; Glycopeptides; Digestion; HPLC; MALDI-MS;

    Abstract : In this project, separation of trypsin digested transferrin (Tf) has been studied, using a RP HPLC- UV system equipped with a C18 column. 0.1% TFA/MQ-water and 90% MeOH were used as mobile phase A and mobile phase B, respectively. READ MORE

  6. 25. Optimizing purification of oligonucleotides with reversed phase trityl-on solid phase extraction

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Ninorta Bartuma; [2019]
    Keywords : Oligonucleotides; purification; trityl-on; SPE; AIE-HPLC;

    Abstract : Oligonucleotides are synthetic strings of DNA or RNA used mostly for biochemical analysis and diagnostics. For them to be useful in these fields, a purity over 90% is most often required. However, when synthesizing these sequences, many “failures” (shorter sequences) are made in the step-wise process.
