How Can Nitrogen Gas Be Produced in a Laboratory?

Hey. Is anyone able to guide me as to how nitrogen gas can be produced in a laboratory, or give me links with information? I can't seem to find anything :(

Thanks,
Dan.

danago, small amounts of nitrogen gas can be prepared by combining and gently warming a mixture of ammonium and nitrate salts:

NH4Cl + NaNO2 --> N2 + NaCl + H2O, using ammonium chloride and sodium nitrite
