Sulfur hexafluoride (SF6), whether pure or mixed with inexpensive inert gas, has been widely used in a variety of industrial processes, but it is one of the most potent greenhouse gases. For this reason, it is necessary to separate and/or collect it from waste gas streams. In this study, we investigated the pure SF6 and SF6-N2 mixture gas hydrates formation(More)
Human epidermal growth factor (hEGF) secreted by recombinant Escherichia coli was purified from culture broth by expanded-bed adsorption (EBA) chromatography, strong anion-exchange chromatography and finally preparative reversed-phase HPLC (RP-HPLC). The EBA chromatography step simultaneously captured the hEGF by cationic exchanger and removed the cellular(More)
