At GSI, Darmstadt, Germany we use the in gas-Jet Resonant Ionization Spectroscopy (JetRIS) apparatus [1] to perform laser spectroscopy of elements in the heavy actinide region to determine their atomic and nuclear properties. JetRIS presently utilizes $\alpha$-decay detection to maximize sensitivity while minimizing the background from unwanted ions. However, for long-lived nuclides (t$_\frac{1}{2}>$ 10 h) a decay-based detection will not be practical. Thus, a multi-reflection time-of-flight mass separator (MR-ToF MS) is being developed for the JetRIS apparatus, allowing a separation of ions according to their mass-to-charge ratios with a high mass-resolving power, opening the possibility of mass-selected ion detection. This will also allow measuring $\beta$-decaying species and long-lived isotopes. An overview of the MR-ToF MS design and its integration into the system will be given. Prospects for future measurements will be discussed.
