Solid phase extraction apparatus uses glass vials or tubes for sample collection and concentration. Some sorbents require large desorption volume than small SPE cartridges in such case SPE tubes were used.
Application
Empty polypropylene SPE tube with PE frits was used in preparing multi-walled carbon nanotubes (MWCNT) cartridge to perform SPE.
