The 10-port valve is rated for 1 million injections. The 131/132 can be fitted with one or two columns depending on components of interest. For heating values based on C6+, column 1 lets all components pass except C+ and heavier and column 2 measures all other lighter components. The heavier components are measured as a back flush peak during the sample injection part of cycle. Analysis time with single valve for C6+ will be 10 minutes. Analysis time for single or dual components will vary from 2 to 3 minutes.
