matrix-matched calibration

https://doi.org/10.1351/goldbook.10180
Calibration employing external calibration in which standard solutions of target are prepared in a solution of analyte-free matrix.
Note: Matrix-matched calibration is used to minimize the matrix effect on the measurement of target measurands.
