  • Page 51: Drying Gas Supply

    5 Putting into operation Drying gas supply The kind of drying gas supply (air or inert gases) depends on the kind of processed sample mate- rial. There are significant differences between ‘open loop’ and ‘closed loop’ configuration of supply and exhaust gases. Strictly follow the configuration descriptions in this section as well as the defined proper and improper use in section 2 for safe operation.

  • Page 52: Open Loop' Air Supply Configuration

    To ensure the optimal drying air performance in this opera- tion mode, the supplied air has to be dry and free of impurities. If this can not be guaranteed, BUCHI recommends the use of a Wilkerson air maintenance unit (see next picture).
