A rapid impregnation method for loading desired amounts of extractant on prepacked reversed-phase columns for high performance liquid chromatographic separation of metal ions.
Ramzan M, Kifle D, Wibetoe G. Ramzan M, et al. J Chromatogr A. 2017 Jun 2;1500:76-83. doi: 10.1016/j.chroma.2017.04.005. Epub 2017 Apr 7. J Chromatogr A. 2017. PMID: 28431687
The chromatographic traits for separation of the lighter lanthanides (La-Gd) using columns impregnated under different conditions were evaluated; heating for short period of time gave improved column performance most likely due to the presence of n-pentane in the pores of the sup …
