I am currently making a machine thing where HYGN is split by PHOT into PROT and ELEC. I need to be able to filter out the PROT, letting only the ELEC to pass through.

I have already made this thing where the ELECtrons are the ones filtered out (using QRTZ), leaving only Protons.

Edit: If this helps, I have already figured out a way to convert ELEC to PHOT (light, white stuff) using GLOW. I can't find an element that will stop PROT (red stuff) but permit PHOT/ELEC.

Any help?
