use a gas lock syringe available in market (it locks the gas in syringe under different pressure)/ or use normal syringe under atmospheric pressure. Take the gas in the syringe and inject in G.C. Use a stainless steel column packed with Porapack Q/ Carbowex 80/100 mesh (2 m X 3.53 cm X 2 mm) with Argon as carrier gas
