Precision mass measurements of neutron-rich rhodium isotopes have been performed at the JYFLTRAP Penning trap spectrometer Ion Guide Isotope Separator On-Line (IGISOL) facility. We report results on ground- and isomeric-state masses in $^{110,112,114,116,118}\mathrm{Rh}$ very first measurement $^{120}\mathrm{Rh}$.
