Abstract:
1. A synchronous acquisition system for a multi-dimensional orthogonal liquid separation system comprising: a liquid sample inlet; a first liquid separating column including controlled valves; a data acquisition clock providing clock output signals; a data acquisition circuit coupled to said clock for receiving clock pulses therefrom and for providing controlled output signals synchronized with said clock pulses to said controlled valves of said first column; a modulator valve control circuit coupled to said data acquisition system for receiving clock pulses and control signals therefrom; a multi-dimensional separation modulator coupled to said modulator valve control circuit for receiving synchronized valve control pulses therefrom; a second liquid separating column coupled to said multi-dimensional separation modulator for receiving time synchronized pulses of liquid samples; and a detection circuit coupled to said second liquid separating column for providing data output signals to said data acquisition circuit which are read in synchronous relationship to the liquid sample peaks from said second liquid separating column.
