Curve Concentration Calibration Glucose Substance Unknown Define Term

A calibration curve is a graph relating an instrument's response to a substance's concentration, used to determine the concentration of an unknown sample by comparing it to known standards.

Una curva de calibración es un gráfico que relaciona la respuesta de un instrumento con la concentración de una sustancia, utilizado para determinar la concentración de una muestra desconocida comparándola con estándares conocidos.

Front Define the term calibration curve and explain how they are used to identify concentration of glucose in a solution.
Back Calibration curve - method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.
  • Plot that shows how the instrumental response to changes with concentration of substance being measured
  • We can then match the corresponding y coordinate with the curve to find the glucose conc
