Valve 1 V1 is used for sample injection and Valve 2 V2 is configured for column backflushing Both valves are air actuated but V1 is controlled by a Valco Digital Valve Interface DVI while V2 is controlled by a pair of 3 way solenoid valves MSVA Each valve requires two intervals of the DVSP one for clockwise rotation and one for counterclockwise All references to direc tions are as seen from the actuator end of the valve In the ready rest state both valves are in the counterclockwise position Figure 8 After the process is begun by charging the sample to V1 V1 will be switched clockwise to inject the sample Figure 9 After two seconds for sample injection V1 is returned to the counterclockwise position to load the next sample In this example fifteen minutes will elapse before V2 is switched clockwise and the contents of the column are backflushed to the detector Figure 10 After nineteen minutes for desorbtion of the column contents into the detector V2 is switched counterclockwise for the next sample analysis Four and a half minutes will be allowed for equilibration before the next cycle begins V2 CARRIER IN SAMPLE OUT SAMPLE IN TO DETECTOR Figure 8 V1 and V2 Figure 9 V1 Figure 10 V2 in in counterclockwise clockwise clockwise position position position Rest and Intervals 2 4 Interval 1 Interval 3 Broken down into its component intervals the process appears like this Int
