The upper layer of the atmosphere surrounded by ozone (15 to 30 Kms) is known as ozonosphere. Ozone layer is a protective stratospheric layer‚ also known as ozone umbrella. Ozone concentration differs by about 10 ppm in stratosphere compared to 0.05 ppm in troposphere. It acts as a protective shield for the man‚ animals and plants by filtering out the lethal ultraviolet rays from reaching the earth’s surface. If the ozone layer is not there‚ the harmful ultraviolet rays will reach to the

Experimental Thin Layer Chromatography The amino acid standards used in this experiment were Alanine‚ Glycine‚ Serine‚ and Histidine. These standards and the unknown were separated by performing a method of chromatography. Thin layer chromatography (TLC) was performed by using a mobile phase and a stationary phase.

Five-Layer Density Column A density column consists of layers of liquids of different densities which do not mix with each other‚ and which are clearly distinguishable from each other. The highest density material is at the bottom of the column‚ and as you proceed up the column‚ the density of each successive layer decreases‚ with the lowest density layer on top. Three methods for construction of a five-layer density column are discussed in this write-up. All methods use the same five liquids. •
