Hello James,

you're remembering correctly. The articles title is "Analysis of Peptide
and Protein Samples Containing Surfactants by MALDI-MS", published in Anal.
Chem. 1997, Vol. 69, pp 1102-1106. The Authors are Amado, Graca
Santana-Marques, Ferrer-Correia and Tomer. Hope this helps.

Yours sincerely,
Marcus Macht
