Yes, this is how it is done. Scientists look for chemical gradients as indicators of the presence of life in extra-terrestrial environments. Life inherently involves the use of chemical energy to isolate chemical reactions, thus improving the thermodynamic likelihood for a successful reaction. This involves spatial separation of compounds. Chemical equilibrium is not a sign of life as we understand it.
