Different instrumental calibration procedure.

Question

Accepted Answer

Instrumental calibration procedures ensure accurate and precise measurements. Different procedures include external calibration, internal calibration, and standard addition.

External calibration involves using a standard solution with a known concentration to calibrate the instrument.
Internal calibration involves using a reference material that is added to the sample to ensure accurate measurements.
Standard addition involves adding a known amount of a standard solution to the sample to determine the concentration.
Calibration curves can also be used to determine instrument response and accuracy.
Regular calibration is necessary to ensure reliable results and prevent errors.
