Analytical Reflective Essay

Introduction: Chromatography is a technique used by scientists to separate a mixture, known or unknown, into each component present in the mixture. For chromatography to be completed there has to be a mobile and stationary phase present. The mobile phase in chromatography is any liquid or gas containing the substance to be separated. The stationary phase acts as a magnet in which certain substances will be more attracted to than others and each different component will travel up in a unique pattern

Electrospray is the technique that is used by analytical chemist for the creation of ions from a sample. The technique uses electricity to form an exceptionally fine liquid aerosol. Other techniques that were used before electrospray used gas to form these aerosols for analyses. Electrospray is particularly useful over using gas because it is a soft ionization technique. Soft ionization techniques ionize the sample with minor fragmentation of the molecule, giving an observable molecular ion for the

Management of implementation of nanotechnology in upstream oil industry: An analytic hierarchy process analysis Pouyan Motamedi1*, Hasan Bargozin2, Peyman Pourafshary3 1 Department of Chemical and Materials Engineering, University of Alberta, Edmonton Alberta, Canada 2 Department of Chemical Engineering, University of Zanjan, Zanjan, Iran 3 Department of Petroleum and Chemical Engineering, Sultan Qaboos University, Muscat, Oman Abstract Nanotechnology has had revolutionary effects in various fields

Introduction Proteinuria is often used to detect the presence of any type of proteins in the urine and serves as a diagnostic tool for renal disease and hypertensive disorders. Among those disorders, pre-eclampsia is characterized by low renal perfusion and leakage of proteins in urine due to a damaged glomerular base membrane (1). This condition is associated with a high risk of maternal complications and prenatal mortality. Pre-eclampsia is usually defined as a combination of hypertension, edema

Introduction to Gas Chromatography Jeffrey Palumbo ID: 20523300 Chem 224L Section 003 Partner: Victor Łotocki Date of Experiment: June 17, 2015 Introduction Gas chromatography is a common separation technique used in analytical chemistry to separate, identify and quantify the compounds present is a sample (Harris, 2010). The purpose of this experiment is to analyze a sample of TEX (toluene, ethyl benzene, and o-xylene) and identify the peaks from the resulting chromatogram. Another objective

Human mind is a very complex structure like a snow crystal. No two crystals are same but the patterns are repeated. To completely understand a person, the various facets of their nature are needed to be explored. Carl Jung had illustrated the human character as the combination of many archetypes, those which are dominant in the conscious nature and also those which are underlying within a person without the knowledge of its presence. These archetypes are the building blocks of a unique character

seemingly ordinary objects by using a few reagents. I became a regular follower of such shows and thus began my love for Chemistry. During my undergraduate studies, I discovered that Analytical Chemistry formed the backbone of these so-called magical techniques,which further influenced me to get a higher degree in Analytical Chemistry. Another topic that gave me inspiration toward chemistry was sustainability of energy and environment. Being a citizen of a developing country, I observed energy crisis

A Soxhlet extraction is used only if the desire substance we want to extract from the sample has limited solubility in a particular solvent, and the impurities cannot dissolve in the solvent. The purpose of this experiment is to extract nicotine from tobacco samples and calculate the amount of nicotine in it. In this experiment, nicotine will be the substance we want to get, and dichloromethane will be the solvent. Through several cycles of extraction, nicotine was able to dissolve in the solvent

THE USE OF CHEMISTRY SEPERATION TECHNIQUES IN FORENSIC SCIENCE “Poisons were employed by early Egyptians and ancient Greeks and Romans. The Blandy trial of 1752 was the first instance of an actual chemical test for poison, and the Marsh test, developed in 1836, was the first reliable analysis that could show scientifically that arsenic was present in the body of a victim. This meant the revolution of applying science to questions of civil and criminal law.” Chemistry Explained (2015) Advameg, Inc

connection, it will stick with the stationary phase. This distribution ratio among the selected phases must differ for each sample compound in order for them to separate. Types of Chromatography: Paper Chromatography: Paper chromatography is a analytical technique in which the mixture is
