| The chromatographic column is placed in a thermoregulated container, so that optimal temperature conditions are created. |
| Molecular fossils are recovered and studied using chromatographic techniques, mass spectrometry, and spectrophotometry. |
| Modern methods for measuring molecular weight include chromatographic methods and mass spectrometry. |
| Homozygotes and heterozygotes at individual sites were distinguished by their chromatographic patterns. |
| The extract is then carefully fractionated by chromatographic separation methods. |
| The foam is consequently difficult to handle, and protein separation by conventional chromatographic methods is only partially successful. |
