## Abstract The key to enhanced electron‐capture negative ion mass spectrometry (ECNI‐MS) response of ketosteroids is extensive α,β‐unsaturation. Combinations of double bonds, carbonyl groups, epoxides and halogens within a steroid nucleus were correlated with their ECNI responses. The greatest ECN
When we subjected l l-dehydrothromboxane B 2 (II-DTXB2) , a metabolite of arachidonic acid, to standard chemical derivatization procedures we obtained a mixture of several products. Separation of the components was carried out by gas chromatography and their identification was accomplished through t
