Mass-independent Cr isotopes are powerful tracers of early solar system evolution. We developed a rapid and high-yield purification method applicable to small samples (＜5 mg). A combination of multi-acid digestion and three-step column chemistry achieves >95% Cr recovery within one week. This technique enables precise Cr isotope analysis of rare planetary materials with minimal sample consumption.
