Suitable combinations of an ordinary scalar and a time-like component of a Lorentz violating vector coupling allow for a split into \"matter\" and \"antimatter\" couplings, at least in the non-relativistic limit. By considering hydrogen and antihydrogen spectra, we access both matter and antimatter couplings.
