Summary The molecular weight of various steroids (sterols, steroidal sapogenins, and alkaloids) as well as the molecular weight distribution in complex mixtures of similar steroids, has been exactly determined by application of ‘molecule mass spectrography’. In this technique, negatively-charged (p − 1) ions are formed, usually without further fragmentation. The advantages and new possibilities of this method are discussed.
