Using an Additional <strong>819</strong> <strong>Module</strong> for Fraction Collection<br />
At Initialization<br />
The default position for the second <strong>819</strong> valve is the<br />
INJECT (collect) position. Before samples can be<br />
injected, the <strong>819</strong> collection valve must be toggled<br />
from the INJECT (collect) position to the LOAD<br />
(drain) position. To change the valve to the LOAD<br />
(drain) position, use the Manual Injector Control<br />
dialog in the Operations window. Or, you can add<br />
the Set Low Pressure Valve command to the start<br />
of the control method or to a startup method to<br />
ensure that the valve will be in the correct position<br />
at the start of the run. Refer to the examples on the<br />
next page.<br />
