ABSTRACT:
The invention concerns a separation column in microsystem technology for a gas chromatograph comprising a first substrate, a second substrate which is arranged on the first substrate, wherein a trench structure is provided in at least one substrate and the trench structure is sealed off relative to the environment, a stationary phase applied at least to parts of the trench structure, a gas inlet connected to the trench structure, and a gas outlet connected to the trench structure.
