GDMS AP6Ce (click images to view larger)

The GDMS AP6Ce is a six-channel gas delivery and mixing system that employs a modular, needs-driven approach and is also available in multiple configurations for all gas dilution and delivery requirements. The GDMS AP6Ce is fully automated and easily programmed via an embedded computer with a touch screen interface. Real-time diagnostics and feedback control, including visual display of active gas flow paths and dilution/mixing conditions, provides a total system status to the user and eliminates programming errors/conflicts. The GDMS AP6Ce is the solution to your laboratory gas testing and delivery needs.

The GDMS AP6Ce allows for six gas inputs with three independent input mixing mass flow controllers (MFCs), one dilution MFC, one purge MFC, one interferent MFC, and a single output post-mixing MFC.  The system also includes a pre-charge mixing manifold to virtually eliminate time delays between input gas selection and output exposure.  The embedded touch-screen PC allows for ease-of-programming and ease-of-use (sample interface menus are shown below).  There are also two USB ports and a LAN connection.  The GDMS AP6Ce was designed as a universal gas delivery and mixing system that is easily configurable and adaptable to a wide range of applications.
