CE ÎNSEAMNĂ CHROMATOGRAM ÎN ENGLEZĂ?
Prin cromatografie
Cromatografia este termenul colectiv pentru un set de tehnici de laborator pentru separarea amestecurilor. Amestecul este dizolvat într-un fluid numit fază mobilă, care îl transportă printr-o structură care deține un alt material numit fază staționară. Diferiții constituenți ai amestecului se deplasează la viteze diferite, determinându-i să se despartă. Separarea se bazează pe împărțirea diferențială între fazele mobile și cele staționare. Diferențele subtile în coeficientul de partiție al compusului determină retenția diferențială pe faza staționară și modificând astfel separarea. Cromatografia poate fi preparativă sau analitică. Scopul cromatografiei preparative este de a separa componentele unui amestec pentru o utilizare mai avansată. Cromatografia analitică se face în mod normal cu cantități mai mici de material și este pentru măsurarea proporțiilor relative ale analitilor dintr-un amestec. Cele două nu se exclud reciproc.
Definiția chromatogram în dicționarul Engleză
Definiția cromatogramei în dicționar este o coloană sau o fâșie de material care conține componente ale unui amestec separat prin cromatografie. O altă definiție a cromatogramei este un grafic care arată cantitatea unei substanțe lăsând o coloană de cromatografie în funcție de timp.
