Adsorption characteristic study of activated carbons down to 4.5 k

Abstract Adsorption characteristic study of different activated carbon samples are performed at low temperature down to 5 K by using cryocooler based low temperature facility with a micropore analyzer. This facility is now operational at Institute for plasma research (IPR). It comprises of a commercial micro pore analyzer for sample characterization at 77 K and a GM cryocooler cooling unit forholding the sample at any temperature 2 /gm (at 4.5 K), and it increases with lowering the temperature down to 4.5 K from 77.0 K.
