摘要: We describe the construction of an apparatus for production a molecular jet microhydrated biomolecules. Our design uses water reservoir producing vapour, which then passes through separate containing vapour sublimated biomolecule. The mixture coexpands into beam conical nozzle. Mass spectra showing water-adenin and water-uracil complexes are shown as typical examples. Suitable expansion conditions reached without use inert carrier gas.
