| Abstract: | Lecithins directly introduced on a gold wire near the electron beam under ammonia chemical ionization conditions, give mass spectra showing the (M + 1)+ ion and ions of structurally significant fragments. Of particular interest is the identification of a substitution-like reaction of ammonia on the head group of the phosphatidylcholines. No instrumental modifications is required. |
