Disposal32
Chromatografické zvyšky: agresívne, výbušné (napr. peroxidy) a jedovaté látky chromatografických vrstvách a sorbentoch sa pred zneškodnením musia eliminovaťvhodnými metódami (vypláchnutie, elúcia). Rozpúštadlá použité na elúciu je v mnohých prípadoch možné opäť použiť. Z väčších množstiev sorbentov (napr. z kolón) odstráňte rozpúšťadlá (filtráciou, vysušením) a zabaľte sorbenty do odolných plastových vreciek: nádoba I. TLC stojany a kolóny zneškodnite spolu s príslušnými odpadovými látkami (hliník, sklo, plasty): nádoba K.
