A vertical glass tube used in column chromatography; a mixture is poured in the top and washed through a stationary substance where components of the mixture are adsorbed selectively to form colored bands.
Classification
Nouns denoting man-made objects.
Examples
- The liquid mixture was poured into the chromatography column, and the solvent flowed down, separating the components.
- After pouring the sample into the chromatography column, it was clear that the column needed to be eluted to confirm the separation of the mixture.
- Column chromatography was performed using a glass chromatography column packed with silica gel as the stationary phase.
- The solvents used in the experiment flowed too slowly through the chromatography column and did not separate the mixture within a reasonable amount of time.
- In a thin layer chromatography system, a long glass chromatography column was substituted by a silica-coated plate to carry out the process.
