elute

Thân thiện

The chemist elutes the colored compounds from the column.

Definition

Verb: To separate or wash out (a substance) from a material by passing a solvent through it. This process is particularly fundamental in chromatography, where a mobile phase (the solvent) moves through a stationary phase, carrying different components of a mixture at different rates to separate them.

Usage

The verb "elute" describes the specific action in a separation process where a solvent causes adsorbed substances to move from a solid medium. It is primarily used in scientific contexts, especially chemistry and biochemistry.

Examples

• Verb:
  • The goal is to elute the protein from the column using a buffer with a high salt concentration.
  • In this experiment, we will elute the compounds with a gradient of increasing solvent polarity.
  • The desired component was successfully eluted after ten minutes.

Advanced Usage

• "to elute something from something": This is the standard construction, specifying both the substance being removed and the medium it is removed from.
  • The researcher needed to elute the antibiotic from the resin for further testing.

Variants and Related Words

• Elution (n): The process or result of eluting.
  • The elution profile showed two distinct peaks.
• Eluent (n): The solvent or solution used to carry out the elution.
  • The chosen eluent was a mixture of water and methanol.

Synonyms

• Wash out: To remove by the action of a liquid (less technical).
• Extract: To remove a substance, often implying a general removal rather than the specific chromatographic process.

Antonyms

• Adsorb: To accumulate (a substance) on a surface in a condensed layer.
• Bind: To become attached or fixed to a surface.
