Principium ultrasonic extraction
Ultrasonic fluctus propagare per liquidum media, producendo a "cavitation effectus" in vibrationis. Cavitation effectum forms excelsum - Energy Microbublles, qui dimittis loci princeps temperaturis et excelsum pressuris cum rumpunt, ita:
1.destroying cell muros: promovendi release of intracellular components.
2.Increasing contactus area inter solvendo et sample: augendae dissolutio et diffusio rate.
3.enanching Missam translatio processus: Accelerating translatione activa ingredientia a sample ad solvendo.
Ultrasonic extraction gradus
I. Para rudis materiae:
Cóntere in scopum materia (ut plantae vel aliam solidum samples) ad augendam superficiem area.
Select oportet solvents (ut aqua, ethanol, methanolum vel solits solvents) ut opus.
II. Mixing solvent:
Miscere in sample et solvendo in opportunitate Ratio, plerumque I, V ad 1:20 (sample: solvente).
Place mixtisque in continens repugnant ad ultrasonic vibrationem.
III. Ultrasonic curatio:
Uti Ultrasonic velbe vel ultrasonic lautus.
Set frequency et potentia (communi frequentiis sunt 20-40 khz) et temperatus ad 30-70 ° c.
Et extraction est fere 10-60 minutes, quae potest esse adaequatum fretus in sample et scopum components.
IV. Separatio et purificationis:
Usus centrifugaci, filtration aut separatory infusorium separare solutionem a solidum.
Incumbo, siccum vel plura purificare ex extract (ut columna chromatography).
