    Diffusing Capacity Tests Diffusing capacity test it’s done to measure the lung’s ability to exchange gases through alveolar-capillary membrane by using gas mixture. In this test they assess 3 things to see the efficacy of the lung; 1- Lungs’ surface area with contact diffusing alveoli which is "alveolar volume". 2- Thickness of alveolar-capillary membrane. 3- blood volume available in the pulmonary capillaries. Physiology: In normal lung the gas exchange occur by passive diffusion of the gas via

    plate depends on the polarity of the samples. Because silica is a polar substance‚ nonpolar substances will travel the most since they interact the least with the stationary phase. The plate can then be analyzed to determine the components of a sample. TLC can be analyzed through calculating the Rf factor‚ which is a ratio of a sample’s distance traveled to the solvent’s distance traveled. The Rf value can be used to identify compounds‚ and to determine polarity relative to other
