Critical cont temperature

The most widely used mobile phase for SIT. is carbon dioxide. It is an excellent solvent for a variety of nonpolar organic molecules. In addition, it transmits in the ultraviolet region and is odorless, nontoxic, readily available, and remarkably inexpensive cont-pared to other chromatographic solvents. (Is critical temperature of 31 ( and its critical pressure of 72,9 atm permit a wide selection of temperatures and pressures without exceeding the operating limits of modern FlPl.C equipment. In some applications, polar organic modifiers, such as methanol, are introduced in small concentrations (-1%) to modify a values for analytes.
