Analyte

from class:

Intro to Chemistry

Definition

An analyte is a substance or chemical constituent that is being measured and analyzed in a laboratory sample. It is the target of quantitative chemical analysis to determine its concentration within a mixture.

congrats on reading the definition of analyte. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. The analyte's concentration can be determined using various methods such as titration, spectrophotometry, or chromatography.
  2. In a chemical reaction, the analyte is often the reactant whose quantity is of interest.
  3. Accuracy in measuring the analyte's concentration is critical for stoichiometric calculations in reactions.
  4. Different analytical techniques may require different preparation methods for the sample containing the analyte.
  5. Calibration curves are often used to relate instrument response to analyte concentration.
