Introduction

In May 2012, English couple Mick and Mairead Philpott made the headlines for surviving a fire that killed their six children and destroyed their house in the Allenton area (BBC News, 2013). After publicly claiming to be lucky for surviving the fire, the Philpotts won the sympathy of people who felt sorry for them for losing six of their children and most of their properties. However, after a month of investigation, the Philpotts were accused of committing arson and murder, and by 2013, they were convicted of manslaughter for deliberately starting a fire that killed all six of their ...

Aims and Objectives of the Experiment

The aim of this experiment is to study the separation of an extract of a non-prescription analgesic tablet containing acetylsalicylic acid (aspirin) and caffeine. The separation is achieved through a well-known process called liquid chromatography. The quantities of the aforementioned substances also need to be determined in the experiment (“High Performance Liquid Chromatography,” n.d.).

Theory and Principles

Chromatography is a technique used for the separation of the components, or solutes, in a mixture. The separation is based on the amounts of the relevant solute in the moving, or fluid, stream. There are two phases in chromatography, the mobile phase, and the stationary ...

CO is a major indoor air pollutant, and is released when combustion is carried out in confined spaces such as mines ...

Question 1

Spectrometry would indeed be a good analytical tool since it will help in distinguishing the different compounds in the powder. In such a case, the best type of spectroscopy would be infrared spectrometry and mass spectrometry. Infrared spectroscopy is a vital analytical tool to identify controlled substances. Infrared light is passed on the unknown substance. As the sample absorbs the infrared radiation, an infrared spectrum results, which is a series of peaks and valleys ("Physical Evidence Handbook Drug Identification Unit", 2016). Each substance in the compound results in a highly accurate infrared spectrum. The spectrum of the unknown elements ...

Gas Chromatography-Mass Spectrometry Analysis (GC-MS) is a technique that incorporates chromatographic and spectroscopic techniques in separating and identifying constituents in a sample. According to Erika, Josefina and Maria (2011), the major goal of the technique is in quantifying an amount of a sample, which is done by comparing the relative concentrations among the atomic masses in the produced spectrum. The sample that needs to be quantified is organic and volatile, or semi volatile. The GC part is used to separate is essential in carrying out separation techniques where mixtures are isolated from their constituents using a temperature-controlled capillary column. Smaller molecules in ...
