To construct an internal standard calibration curve, it is necessary to prepare several standards containing different. The internal standards are used to correct for matrix effects (standard addition method with the same analyte added to the sample) or an internal standard different of the analyte, but , the. An internal standard in analytical chemistry is a chemical substance that is added in a constant amount to samples, the blank and calibration standards in a chemical analysis.
