Concepts of 2D-LC
In a 2D-LC-System,
1
D pump generates the
1
D gradient. An autosampler injects
the sample and separates it by
1
D column. A 2D-LC Valve (Injector) connects the
first dimension to the second dimension and stores sample peaks
intermediately. These sample peaks are re-injected to the second dimension,
separated by a
2
D column and measured by the
2
D detector.
