Efficient separation of boron using solid-phase extraction for boron isotope analysis by MC-ICP-MS

An experimental apparatus for ion exchange solid-phase extraction (SPE) was designed to separate boron for boron isotope analysis by MC-ICP-MS. Using the SPE under a pump pressure of up to 0.04 MPa, boron can be efficiently separated from >10 mL water samples with a low boron content.
