Summary of second dimension retention times and standard deviations to which second dimension areas for peaks 1–6 were added to blank LC×LC chromatograms (n = 3).
| Peak # | 2tR (s) | 2σ (s) |
|---|---|---|
| 1a-c | 15.25 | 0.3125 |
| 2a-c | 15.25 | 0.2500 |
| 3a-c | 13.25 | 0.4688 |
| 4a-c | 10.25 | 0.2188 |
| 5a-c | 10.25 | 0.2500 |
| 6a-c | 6.25 | 0.3125 |
Peaks 1a–6a, 1b–6b and 1c–6c are simulated Gaussian peaks with areas determined from the experimentally determined first dimension added to real LC×LC blank chromatograms.
