Gas Tungsten Arc Welding The Process Gas Tungsten Arc Welding‚ also known as Tungsten Inert Gas Welding‚ is an arc welding process that uses a non-consumable tungsten electrode to produce a weld. The weld area is protected from atmospheric contamination by an inert shielding gas‚ such as argon or helium‚ and filler metal is normally used‚ except in autogenous welds. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and

Europe seeks independence from Russian gas imports through shale gas in Poland – Demand shift & Free Market Competition Natural gas in Europe is a major source of electricity generation‚ domestic use (domestic cooking and heating fuel)‚ transportation‚ and is also used in the manufacture of fabrics‚ glass‚ steel‚ plastics‚ paint‚ and other products. Therefore‚ no industrial country can afford to be cut off from this supply‚ because it would result in a major loss of economic power and chaos for

2013 Group No.: 8 Date Submitted: January 6‚ 2014 Experiment 4: Extraction and Chromatic Separation of Plant Pigments from Tomato Paste ABSTRACT In column chromatography a mixture is dissolved in a solvent and poured over a column of solid adsorbent then eluted with the same or a different solvent. This method is often used for preparative purposes; when a relatively large amount of the mixture and the components

Article Analysis Paper – Natural Gas Consumption In order to understand the consumption patterns it is important to understand the principles of Economics and Microeconomics. According to Colander (2010)‚ Economics is the study of the wants and desires of people using their decision making‚ social‚ and political realities in society. Microeconomics is a branch of Economics where we can find the studying of changing consumption patterns. Microeconomics is the study of choices that people make

best. The idea is to be able to isolate the protien that is in interest from the protiens that are not needed. Below are several chromatography techniques that are used to analyze proteins. Size exclusion chromatography (SEC) In this type of technique the protein is separated according to the size of the protein. The matrixes used in size exclusion chromatography have a range of beads with different pore sizes (H. Dai). The seperation of the protein is dependent on how the protein can enter

Column Chromatography ________________________________________________ You have already performed two chromatography experiments: gas chromatography and thin layer chromatography. All chromatography experiments involve passing a mixture of analytes through a system that includes a mobile phase and a stationary phase. The partitioning of the analytes between these two phases determines the rate at which they pass through the system‚ and (in theory) allows them to be separated from one another. Column
