• For direct injection without trapping columns the valve to bypass function
• For Direct Injection Mode using one column and one pump, set the Micro Well
• Pressure drop with injector valve in bypass (e.g. during drawing sample)

must be used after the sample is transferred to the column. This function
results in smaller delay times and sharper gradient curves. The starting
time of the gradient should be coincident with the valve to bypass switch
time for correct sample transfer.
Plate Sampler to use a programmed injection mode and a needle wash.
Using both features, the injected sample reaches the analytical column in
the shortest time and minimizes sample carry-over from the needle.
should be comparable to mainpass mode, otherwise the seat or the capillary
