Abstract
It has been shown that there is no significant carrier effect when low levels of [3H]octopamine (100 pg) are extracted by ethyl acetate from aqueous solutions containing a 10(3) or 10(6) times excess of unlabelled octopamine. It is also shown that there is no carrier effect when low levels of octopamine as the tetrakis-TMS derivative are injected with 100 times the amount of the [2H3] analogue on an SE 30 column.
