Found about 'matrix-matched calibration' without 'standard', don't know if are the same

Determination of pesticide transformation products: A review of extraction and detection methods
In relation to quantification process in targeted compound analysis,
matrix effect can be an important source of errors, and several
strategies can be used. For instance, it was observed that during the
determination of some carboxylic acid TPs in urine [65], a signal
enhancement was noted. The use of isotope labelled internal standards
(IS) is the best choice to compensate matrix effects, but the
lack of standards for most of TPs and their high cost make necessary
the use of alternative procedures, such as matrix-matched standard
calibration. Additionally, if the analytes are present at low concentrations,
other alternatives such as efficient clean-up procedures
are necessary to obtain reliable results.

calibración con patrones de matriz similar a la de las muestras
Explanation:
En este documento de Agilent explican qué son los matrix-matched standards:

http://hpst.cz/sites/default/files/attachments/5991-1182en-o...
"One of the most important aspects is the use of matrix-matched calibration standards, that is, authentic reference materials at known concentrations prepared in blank matrix of the sample types to be analyzed."

Se trata, pues, de patrones preparados con una matriz análoga a la de las muestras que se analizan.

En internet se encuentran otras variantes, más breves, pero en mi opinión menos claras o menos rigurosas, como "calibración en matriz", "calibración con patrones emparejados" o "calibración con patrones similares a la matriz".

Cuatro referencias en castellano en las que también figura la expresión en inglés:
