Term Definition
2D-LC Two-dimensional liquid chromatography
1D One-dimensional
1D-LC is the classical (one dimensional) chromatography, which provides
one-dimensional data. Usually, you would not even think about dimensions in the 1D
world.
1
D
First dimension
For example, a
1
D column is the column used in the first dimension, and a
1
D
chromatogram is the chromatogram acquired for the first dimension.
2D Two-dimensional
2D-LC is two dimensional chromatography, which provides two-dimensional data.
Two-dimensional data is data that has a first and a second dimension.
For example, 2D results can have chromatograms and peaks in each dimension. A 2D
peak has a retention time in each dimension. 2D peaks are peaks in the
two-dimensional contour plot.
2
D
Second dimension
For example, a
2
D pump is a pump installed in the second dimension. The
2
D
retention time is the retention time in the second dimension chromatogram, or the
weighted averaged retention time for the second dimension in a two-dimensional
peak.
2
D peaks are peaks in
2
D cut chromatograms.
