elution

elution
Zelfstandig naamwoord
    • the process of extracting one material from another by washing with a solvent to remove adsorbed material from an adsorbent (as in washing of loaded ion-exchange resins to remove captured ions); used to obtain uranium ions

    Hyperoniemen


    Voorbeeldzinnen

    1. Elution mode:
    2. Elution solvents (4.4)
    3. HPLC elution solvents
    4. Isocratic elution followed by gradient column cleaning:
    5. The rate of elution must not exceed 20 ml/min.
    6. Elution solvents must be prepared using HPLC-grade reagents.
    7. After elution of the sterol esters the chromatogram trace must not show any significant peaks (triglycerides).
    8. Elution buffers, prepared according to conditions for the analyser used (4.9).
    9. after 10 min. gradient elution during 30 min. to: A + B + C = 45 + 20 + 35 (V + V + V)
    10. The following conditions for isocratic elution are offered for guidance; other conditions may be used, provided they yield equivalent results (see also observations 9.1 and 9.2):
    11. It is important that the run time is sufficiently long for the elution of all the degradation products, otherwise late eluting peaks may interfere with subsequent chromatographic runs.
    12. The support material for the column elution method should be inert. Possible materials which can be employed are glass beads and sand.
    13. Leave the remaining methanol for 10 minutes to equilibrate with the resin and continue the elution at a rate not exceeding 20 ml/min. collecting the eluate in the same round-bottomed flask.
