As the first time the evaporation behaviour of trimethylindium‐trimethylamine (TMIn‐TMN) was investigated with a flame ionisation method. Individual metalorganic components can be detected in rather low concentrations (10 −2 Torr) in a hydrogen carrier gas. A reproducible and constant supply could be realised with the solid TMIn‐TMN‐adduct in accordance with the equation for the vapour pressure: Ig p = −2597 · T −1 + 8.748 ( p in Torr) in the temperature range 273 K < T < 294 K. 99% of the steady state value of TMIn‐TMN concentrations in hydrogen was reached within 5–7 min after switching the bubbler into the gasstream.
