“…Currently, most commonly used methods for boron purification are based on ion exchange, gravity column chromatography (Foster, 2008; Foster et al., 2013; Gutjahr et al., 2021; Stewart et al., 2021), and to a lesser extent microsublimation (Buisson et al., 2021; Misra et al., 2014; Rodríguez‐Díaz et al., 2024), batch method (Douville et al., 2010; Lécuyer et al., 2002), and pumped chromatography systems (de la Vega et al., 2020; Wei et al., 2014). The benefit of traditional ion exchange gravity column chromatography techniques lies in the generation of accurate and precise boron isotope data (Gutjahr et al., 2021; Stewart et al., 2021).…”
