1. Elution by increasing ionic strength of the mobile phase is more subtle.2. A Birch reduction of naphthalene takes 5 minutes elution time. 3. This resulted in successful and resolved elution of angiotensin peptides. 4. First, the salt concentration in the elution buffer is gradually increased. 5. The larger the particles, the faster the elution . 6. The first few elutions will have reduced effectiveness because of this high ratio. 7. In conventional chromatography, separation of similar compounds can be improved by gradient elution . 8. The actinide elution sequence is reversed from that of the cation-exchange resin column. 9. Usually a gradient ( to increasing amounts of water ) is enough to promote elution . 10. In 1863 Scheibler invented the elution method.
