We investigate a one-dimensional wire of interacting electrons connected to semi-infinite leads in the absence and in the presence of a backscattering potential. An incident electron on the clean wire is perfectly transmitted into spatially separated spin and charge parts in the noninteracting leads, a result we extend to any finite-range interactions. The backscattering potential is renormalized in a non-universal way and therefore the reduction in the conductance is more complicated than the laws derived up to now: it has power laws as a function of temperature, wire length, and also the distance of a barrier to the contacts.
