The Vici valve sequencer (VVS) was designed to steer and automate 8-port C25 Vici Valves, for instance in connection with a PTR-MS volatile profiling system. The program makes it possible to either manually control the valve or program complex time-sequences. Sequences are automatically registered in a log-file to facilitate data deconvolution.
