WebOct 1, 2024 · The OPTIMIZER™ Smart Mini System will be implanted and CCM will be programmed ON for the first 18 months (blinded phase). CCM therapy will be programmed to deliver 7 one-hour phases of CCM therapy that are distributed equally over every 24-hour period. CCM will remain on following completion of the 18-month visit. La chromatographie bidimensionnelle sur couche mince (ou CCM-2D) a deux applications principales : • Aider à mieux identifier les constituants d'un mélange complexe, • Détecter une dégradation d'un composé sur la phase stationnaire.
