Re: Anyone able to do GC or GC-MS on Hp ThinkJet Black ink ( for the Hp ThinkJet 2225 printer; Hp 9226a Or Hp 51604a ink cartridges ) ?

 

A PerkinElmer Elan 6000 - that thing must weigh a ton!? Which Shimadzu unit do you have? Is this for a home lab!?? If so that it is awesome. I hope you're not using H2 for carrier gas lol.??

Sephadex G-25 for affinity chromatography I assume?? G-10 is for small molecule.? I guess it depends on what you're interested in.? Are you looking for more residual solvents? Or understanding more about the dye and/or additional additives?

GC would require a midpolar column.? Something like Agilent's VF-35ms.? Good for resolving aromatics with substituted?polar groups.? Still think it is unlikely you'd be able to find a method that would resolve all components of the dye on GC-MS considering the molar mass of the dye.

Don't think I need an outside lab, .... but would be interested in discuss with those actually having analytical equipment.
(? I still need a few minor parts for my pe Elan 6000,? so that is not ready yet,? lol.? And yes, I would need a different column for the Shimadzu, sigh. )

But, am betting that this ink issue can be solved more easily:

My next practical step, after having tried some TLC plates, will be to try one of the inexpensive Sephadex columns,
Will start with either G-10 or G-25, and then possibly proceed forward, with a more specific column.
