Tested with an iontopicks Aurora Elite XT 15 cm column (https://ionopticks.com/product/aurora-elite-xt/) but should work with all other XT columns as well. The second holder is designed for Phoenix S&T liquid junctions (https://www.mswil.com/catalog/column-ovens/liquid-junction-pst-hv-nfu/) and holds the hexagonal metal junction once removed from the insulating rubber holder.
The ionopticks emitter or the Phoenix liquid junction are inserted into the holder from the top so that solvent can drip from the emitter.
Printed with .4mm nozzle using PLA.
