Hai cercato: Colonne cromatografiche
Chromatography columns separate molecules within mixtures during gas or liquid chromatography. Filled with stationary phase compositions or chemical compounds, the prepacked options reduce the preparing time required. The vertical pieces are able to withstand extreme temperatures and pressure fluctuations experienced when the mobile phase is forced through the medium. Meet preparative and analytical laboratory procedures with the chromatography columns to separate dissimilar moving components based on individual solvent polarity, composition, and size. The right chromatography control system allows to automate the delivery of cleaning, sanitizing and conditioning buffers to the packed column, and can enable to cycle the chromatography column several times during the batch, requiring smaller columns and subsequent lower capital investment.

Estrazione liquido-liquido, Extrelut® NT
Supplier: Merck
EXtrelut® NT è una speciale terra di diatomea, inerte, con pori larghi e ampio volume poroso. È stata utilizzata per lungo tempo nella ricerca, per la preparazione di campioni di urina, sangue intero, plasma e altre matrici biologiche. Altre applicazioni includono test dei residui e ambientali, quali l'analisi delle acque industriali, domestiche e reflue. EXtrelut® NT è disponibile già confezionato in cartucce o come sorbente sfuso. EXtrelut® NT semplifica l’estrazione liquido-liquido sostituendo gli imbuti separatori. L’uso di un singolo passaggio rende l’operazione più efficiente e consente di risparmiare solvente, oltre che materiale e tempo, rispetto alla separazione con imbuto. È sufficiente applicare il campione acquoso al sorbente EXtrelut® NT. Questo si distribuisce sulla matrice chimicamente inerte, agendo come una fase stazionaria. Successivamente, l’eluizione ha luogo utilizzando solventi organici non miscibili con acqua. Tutte le sostanze lipofile vengono estratte dalla fase acquosa alla fase organica.

Colonne HPLC, SeQuant® ZIC®-pHILIC
Supplier: Merck
La colonna ZIC®-pHILIC ha la stessa fase stazionaria del tipo ZIC®-HILIC, ma è basata su una particella polimerica che aumenta la stabilità del pH. In pratica, la mancanza di silice annulla il background in rilevatori ad alta sensibilità, come ad esempio aerosol caricato utilizzato per determinare ioni organici e inorganici.
