Abstract

Work in this lab has recently focused on developing a method by which mixed self- assembled monolayers (SAMs) of alkanethiols on gold surfaces may be quantitatively analyzed by electrospray ionization mass spectrometry (ESI-MS). The approach that is currently being developed involves the use of hydrogen peroxide to oxidatively remove these films for direct infusion into the electrospray source. The rationale for these ...
