We present new abundance determinations for the sharp-lined HgMn star \chi{} Lupi A from archival FEROS spectra. Selected unblended lines with accurate atomic data have been synthesized to derive new abundances for \chi{} Lupi A. These spectra show evidence of the presence of blue-shifted lines of the companion \chi{} Lupi B. The synthesis of the spectrum of \chi{} Lupi B confirms that this star is cooler, probably an early A star with normal abundances.
