Question 1 1.1 Silica gel chromatography: This is known as the stationary phase in column chromatography. Firstly, the tapered exit of the column is sealed using porous material. This porous material serves as support for the packing material, and prevents it from exiting the pipe. Thereafter, silica gel is compacted into the glass pipe to make the separating column. In finishing preparation of the column, the solvent which is used as the mobile phase is then passed through the dry column. Then the
Biology Report 6 Name : Tan Mei Jing Student No. : 2017141025 Subject : Paper Chromatography Group : 2 Date of Experiment : 31/10/2017 Date of Submission : 2/11/2017 Objectives To understand the principle and mechanism of paper chromatography. To investigate (and separate) the different pigments present in lettuce leaves by using the paper chromatography technique. Hypothesis Lettuce contains mostly chlorophylls (both α and β) for the green color. Results
The cause of death (COD) is as what the crime scene suggests: a drug overdose. It seems that the case is quite clear: the case seemed pretty open and shut; a drug addict simply overdosed or the amount of drugs she took this time, went over what body was able to tolerate and died. However, our meticulous investigators found that most long time drug addicts will
electrophoresis. Plate Heights in CE In chromatography, both longitudinal diffusion and mass-transfer resistance contribute to band broadening. However, because only a single phase is used in electrophoresis, in theory only longitudinal diffusion needs to be considered. In practice, however, Joule heating can add variance as well as the injection process. Although CE is not a chromatographic process, separations are often described in a manncr similar to chromatography. For example, in electrophoresis,
UV-Vis spectroscopy and chromatography. The relative concentrations of anthocyadins in each sample in order of blueberry, raspberry, and blackberry: 3.6 x 10^-5 mol/g, 1.0135 x 10^ -5 mol/g, and 5.8 x 10^ -6 mol/g. The blueberry was found to have the highest concentration and quantity of anthocyanins, followed by the raspberry, and lastly the blackberry
characterized by invitro in order to determine the benefits of the suspension of Mycophenolate mofetil over its solution form. The results have shown that aerosolization performance of both formulations were excellent. 24 hour single dose, pharmacokinetic studies followed by the inhalation both formulations and oral cellcept® administration were performed in rats. Mycophenolate mofetil was rapidly and completely metabolized into the active metabolite by oral drug administration where as partial and slow metabolism
THE EXPLORATORY STUDY OF PHYSICAL AND CHEMICAL PROPERTIES OF RAINWATER IN THE THREE SELECTED BARANGAYS OF MARIKINA CITY By: Francis Eisen C. Bagsic Review of Related Literature Rain acts as a powerful mechanism to remove pollutants from the atmosphere.. Precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. Rainwater composition is important in evaluating the role of transport of soluble material and the contribution of different sources
from the laboratory experiments which gave me the opportunity to use a variety of laboratory techniques for instance; Gel electrophoresis, infrared spectroscopy, and the three types of chromatography which I believe are essentials in the Forensic Science field. As well as gaining knowledge in the science area, my study in Applied Law has given me an insight to the many aspects within the law field from the hierarchy of the court systems to how the court and legal systems work. Applied Law has made
is proportional to the level of exposure but both humans and animals have suffered because of these compounds. Melamine tableware, including plates, bowls and cups etc., are used in daily life due to their durability and ease of use, especially in case of children. However, a recent epidemic of melamine poisoning in China brought up the issue of melamine toxicity due to tainted milk powder formula and it became clear that food contact materials having melamine are not as safe as they were once thought
4.7 Sampling technique 138 type 2 diabetics who met the study inclusion criteria and willing to participate in the study were selected. Using computer generated random number; they were randomly allocated into control group or experimental group (69+69). It is done by allocation of participants by randomization schedule and sealed envelope method. Randomization chits were made and were kept in sequentially numbered small envelops. The random schedule was generated through computer for 138 participants
