Backround: Gas Chromatography separates organic samples much in the same way as column chromatography. The only differences are that it uses a moving gas phase and a stationary liquid phase‚ and that the temperature of the gas system can be controlled. In a gas chromatograph the sample is shot in with a syringe and is immediately vaporized in a heated

we are immensely interested in solutions‚ especially liquid solutions. Solutions are defined as homogeneous mixtures of pure substances in which no precipitation or settling occurs. We often think of solutions as liquids‚ but we can have solutions of solids (alloys)‚ gases (air is a solution of nitrogen‚ oxygen‚ carbon dioxide‚ and a number of other gases)‚ and a combination of states such as liquid and solid metals (amalgams) and liquids and gases (nitrogen in the blood‚ carbonated beverages)

pumping storm water in civil and environmental. They are an integral part of engineering and an understanding of how they work is important. Pumps are devices that transfer mechanical energy from a prime mover into fluid energy to produce the flow of liquids. There are two broad classifications of pumps: positive displacement and dynamic. Dynamic Pumps Dynamic pumps add energy to the fluid by the action of rotating blade‚ which increases the velocity of the fluid. Figure 1 shows the construction
