Abstract
The system described incorporates two pneumatically operated changeover valves, of a new design, with electrically heated capillaries in the dual-inlet system, which reduce the instrumental effects of this system to a negligible level. The changeover valves show many advantages such as high accuracy of closure, fast establishment of steady conditions after switching, simple construction and automatic control. Information on installation of stainless steel capillaries is also included.Keywords
