  • Analysis Of A HPLC Pump

    compound with high reproducibility. The materials for constructing a HPLC column are inert to the analytes such as polished stainless steel, glass and PEEK polymers. There are mainly four types of columns used in HPLC which are high performance analytical column, preparation column, capillary column and…

  • The Principle Of Centrifugation

    like molecular weight, density, shape, etc. If it is used for the separation of one type of materials from others is termed as preparative centrifugation and when used for measurement of physical properties of macromolecules, then it is known as analytical centrifugation. Principle of centrifugation: Particles suspended in a solution are pulled downwards by Earth’s gravitational force. In a solution, particles with higher mass…

  • Bovine Hydrochloric Acid Solution

    have the potential to bind to other proteins. Once this red colored species bind to a protein the bound dye molecule transforms to blue species, and this color change is the one measure by the spectrophotometrical. The assay is a spectroscopy analytical technique based upon the absorbance maximum for an acidic solution of Coomassie Brilliant Blue. From the assay is observed the maximum absorbance for an acidic solution of Coomassie Brilliant Blue G-250 mostly shifts from 465 to 595 nm upon…

  • Analysis: A Jungian Analysis Of Ursula Hegi's Stones From The River

    A Jungian Analysis of Ursula Hegi’s Stones from the River “We cannot change anything until we accept it. Condemnation does not liberate, it oppresses.” - C.G. Jung. Carl Jung’s theories are profoundly influential to modern psychiatry; they allow us to analyze stories, characters, and writings from the innermost layer. Although Carl Jung did extensive research on the human psyche, perhaps some of his most interesting theories were on the nature of how human beings write and tell stories,…

  • Determining The Concentration Of Water Hardness

    Introduction Water hardness is defined as the sum of the concentrations of Ca2+ and Mg2+ in a water sample which is measured by amount of CaCO3. Typically, water hardness indicates the water quality, as hard water has greater concentrations of Ca2+ and Mg2+ and soft water has proportionally less concentrations of the aforementioned ions.1 Water that contains Ca2+ and Mg2+ concentrations above 100 milligrams per liter (mg/L) is categorized as hard while soft water contains ion concentrations…

  • Gravimetric Analysis Colourimetry

    The aim of this experiment was to investigate which technique – out of gravimetric analysis and colourimetry – was the most appropriate and accurate method to practice when calculating the percentage yield of a reaction. When examining the data obtained from the investigation, there was evident that there were some trends in the results. For the three graphs showcasing the results for gravimetric analysis in task one and task two, there was no general pattern. This was due to the fact that in…

  • Light Spectroscopy Lab Report

    Light spectroscopy has become an incredibly useful tool in analyzing the structure and composition of compounds. Specifically, the principles of absorption, the process by which an electron absorbs radiation to excite from a lower energy state to a higher energy state, and fluorescence, the emission of photons when a material is subjected to radiation, allow for the identification and analysis of unknown concentrations of compounds.1 With that being said, the purpose of this experiment is to…

  • High Performance Liquid Chromatography

    Raju Chandra et al; A reliable and reproducible reversed-phase high performance liquid chromatography (RP-HPLC) was developed for the quantitative determination of quetiapine fumarate from marketed bulk tablets. The active ingredient of quetiapine fumarate separation achieved with C18 column using the methanol water mobile phase in the ratio of 30:70 (v/v). The active ingredient of the drug content quantify with UV detector at 359 nm. The retention time of quetiapine fumarate is 5.27 min. A good…

  • Gel Filtration Chromatography Lab Report

    Observe Ligand-Protein Interaction using Gel Filtration Chromatography (Phenol Red Binding to Bovine Serum Albumin) Introduction: Serum albumin is often known as blood albumin, and is the most abundant protein in humans and other animal plasma. Serum albumin is also known as a carrier protein by non-specifically binding several biomolecules. It is essential for maintaining the osmotic pressure that is needed for body fluids distribution between body tissues and intravascular compartments.…
