This function allows you to change the solvent composition at the specified time. Changes in solvent composition occur linearly from either time zero or the time of the last defined change.
When Blend Assist is disabled, you can set the percentages of solvents B, C and D to any value from 0 through 100 %. Solvent A always delivers the remaining volume: 100 - (%B+%C+%D).
When Blend Assist is enabled, you can set the percentages of all solvents or solvent blends except the first channel. The first channel always delivers the remaining amount: (100% - (total percentage of the other channels)).
