\begin{document}$ 270(9)\,~\mu $\end{document}s and \begin{document}$ 121(4)\,~\mu $\end{document}s in the laboratory, respectively. Given that the ground state of 94Ru44+ has a natural lifetime of approximately 75 min, its survival lifetime in the experimental setup was predominantly determined by the beam-loss lifetime, including interactions with residual gas in the storage ring and carbon foil of the detector. In contrast, the survival lifetime of 94mRu44+ was governed by its intrinsic nuclear lifetime and additional beam-loss effects. The nuclear decay lifetime of 94mRu44+ was extracted through differential survival lifetime analysis between ground and isomeric states, under the assumption that the beam-loss lifetimes for both quantum systems are identical. Using this novel methodology, the lifetime measured in the laboratory frame was \begin{document}$ 221(14)\,~\mu $\end{document}s. After relativistic time-dilation corrections, the corresponding rest-frame half-life was calculated to be \begin{document}$ 118(7)\,~\mu $\end{document}s. This result demonstrates excellent consistency with previous experimental results, validating the reliability of the new method. This method is suitable for determining half-lives of highly charged ions in the range of several tens of microseconds to milliseconds using IMS."> A novel method of half-life determination for highly charged ions based on isochronous mass spectrometry -
