Autosampler Principle
Inject-and-Run The final step is the inject- and- run step. The six- port valve is switched to 
the main- pass position, and directs the flow back through the sample 
loop, which now contains a certain amount of sample. The solvent flow 
transports the sample onto the column, and separation begins. This is the 
beginning of a run within an analysis. In this stage, all major 
performance- influencing hardware is flushed internally by the solvent 
flow. For standard applications no additional flushing procedure is 
required.
