Aggregate expenditure is defined as the current value of all the finished goods and services in the economy. The aggregate expenditure is thus the sum total of all the expenditures undertaken in the economy by the factors during a given time period. It refers to the expenditure incurred on consumer goods, planned investment and the expenditure made by the government in the economy. In an open economy scenario, the aggregate expenditure also includes the difference between the exports and the imports.

First, the process of separating the compounds in a mixture is carried out between a liquid stationary phase and a gas mobile phase, whereas in column chromatography the stationary phase is a solid and the mobile phase is a liquid. (Hence the full name of the procedure is ``Gas--liquid chromatography'', referring to the mobile and stationary phases, respectively.) Second, the column through which the gas phase passes is located in an oven where the temperature of the gas can be controlled, whereas column chromatography (typically) has no such temperature control. Finally, the concentration of a compound in the gas phase is solely a function of the vapor pressure of the gas.
 Question: is gas chromatography and gas liquid chromatography the same Context: The first season of the fantasy drama television series Game of Thrones premiered on HBO on April 17, 2011, at 9.00 pm in the U.S., and concluded on June 19, 2011. It consists of ten episodes, each of approximately 55 minutes. The series is based on A Game of Thrones, the first novel in the A Song of Ice and Fire series by George R.R. Martin, adapted for television by David Benioff and D.B. Weiss. HBO had ordered a television pilot in November 2008; filming began the following year.
