Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to

Beer Lambert Law Lab Purpose: The purpose of this lab is to prove the Beer Lambert Law experimentally. The various solutions used for this experiment are tap water mixed with food colouring‚ Introduction: The Beer Lambert Law shows the relation between absorbance of light of an object‚ the molar absorptivity‚ the concentration of the substance‚ and the distance the light travels. The Beer Lambert Law states that there is a linear relationship between the concentration of a solution and the

Induction and Faraday’s Thursday‚ October 25‚ 2012 Lab Report 6 Introduction and Faraday’s Law Objective: In this experiment‚ Faraday’s law of induction will be investigated. Theory: Faraday’s law of induction states the induced emf or voltage in a coil is proportional to the rate of change of magnetic flux through a coil‚ this is shown blew: Ƹ= -dɸ/dt Equation 6.1 The flux of the magnetic field is defined and the following: ɸ=BAcosΘ Equation 6.2
