I've come across some information that suggests BIS-TRIS Propane/1,3-Bis[tris (hydroxymethyl)methylamino]propane and TRIS/Tris(hydroxymethyl)aminomethane are suitable for LC/MS analysis. Buffer ranges for BIS-TRIS 5.8-7.8 and TRIS 7.3-9.3. I try to stay current with possible LC/MS compatible buffers and this is the first time I've come across these. Can anyone confirm?

Thanks,
Phil
