Sample Inject Valve
The sample inject valve enables the system to load a specific, predetermined
volume of sample onto a column.
When the sample pump is installed, the sample inject valve enables the system to
easily switch between manual loop filling, automated loop filling, and direct sample
injection onto a column without replumbing the fluidic connections.
You can use the sample pump to load sample either directly onto a column or into a
sample loop.
