Sodium and potassium salts of organic sulfonates (1‐decyl, 1‐dodecyl and 1‐hexadecyl), sulfates (1‐hexyl, 1‐decyl and 1‐octadecyl) and thiosulfates (1‐octyl, 1‐dodecyl, 1‐tetradecyl, 1‐hexadecyl, benzyl and β‐phenylethyl) were ionized by laser irradiation and the positive ions were analyzed by time‐of‐flight mass spectrometry. The organic ions observed were always intense and due to the molecular species plus a cation or a dimer plus a cation. The spectra of the thioslufates and sulfates show an abundance of inorganic ions in contrast to the sulfonates. The thiosulfate spectra are characterized by intense [Na 3 SO 3 ] + or [K 3 SO 3 ] + ions and the sulfates by intense [Na 3 SO 4 ] + or [K 3 SO 4 ] + ions.
