The LCGC Blog
I've often written about the "lazy" chromatography which has swept through our industry, whereby 0.1% (w/w or w/v!) TFA or formic acid is used to "buffer" the eluent system well away from the pKa of analyte molecules, leaving most acidic analytes in the ion suppressed form and most basic analytes in the ionized form. This approach avoids having issues with retention time drift and effectively eliminates pH as a variable used to control retention or selectivity for separations involving ionogenic analytes.
