    Component seeks to separate‚ identify‚ quantify and analyze the active component found in Biogesic®‚ which may be useful for public awareness despite its wide acceptance and availability in the market. Furthermore‚ this study applies thin layer chromatography (TLC) technique since it is the simplest‚ cheapest yet most effective approach in terms to the study’s objectives. The TLC method implies Rf (Rate of flow) values where it is given by the distance from origin to center of subtance spot over the

    Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase‚ which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds‚ causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound’s partition coefficient result in differential retention

    It was concluded that the product created was paracetamol when a thin layer chromatography test was performed and observed under ultraviolet light (which is discussed further down the page). An unknown substance was treated with acetic anhydrate and resulted with paracetamol. A compound that behaves in this matter is 4-aminophenol and is widespread in the industrial production of this drug. Upon these observations was the build up of “Chemical A” decided.   When 4-aminophenol is t treated with

    Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene
