    Gas Chromatography (GC) Definition: Gas chromatography is a physical method of separation in which the components to be separated are distributed between two phases‚ one being a stationary bed of large surface area‚ and the other a gas that percolates through the stationary bed. When the stationary phase is a solid‚ the separation process is more precisely called gas-solid chromatography. Introduction: Gas Chromatography is a technique widely used to separate complex mixtures of substances. Compounds

    Key Questions Lesson 1 1. One argument against continuing research on the atom is that the cost continues to increase at an alarming rate‚ and the benefits seem to be declining. Whereas quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results‚ now very few if any practical results are emerging‚ but the costs of experiments continues to increase. On the other hand a common argument for the continued
