Under these laws, employees in unionized workplaces are banned from negotiating contracts which require all members who benefit from the union contract to contribute to the costs of union representation.

Gas chromatography is in principle similar to column chromatography (as well as other forms of chromatography, such as HPLC, TLC), but has several notable differences. 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.
is gas chromatography and gas liquid chromatography the same?

The Settlers of Catan, sometimes shortened to Catan or to Settlers, is a multiplayer board game designed by Klaus Teuber and first published in 1995 in Germany by Franckh-Kosmos Verlag (Kosmos) as Die Siedler von Catan.
