Is there a volatile pH 7 buffer that can be used with LC/MS. The only pH 7 buffers I'm aware of are involatile and do nasty things to LC/MS sources.

Ammonium acetate, while it doesn't have the best buffering capacity at pH 7, it will work.

The useful range for Ammonium carbonate is usually given as pH 4-6.
Can you use Triethylammonium acetate (TEAA)?
See also Lee, et al, LC GC Int, 9, 414 (96)
or maybe
Mant. J Liqu Chrom, 12, 139 (1989), but note: TFA is not a buffer.

In response to HW Mueller: Thanks for the tip about TEAA. I looked it up in Fluka's catalog and in the description it stated that TEAA is volatile. I take it that this means no residue is left upon evaporation. Anonymous
