Spanish term

blancos del metodo

Spanish to English Science Chemistry; Chem Sci/Eng Laboratory testing
This is an explanation of quality control methods used in lab testing. I'm unsure of the proper English translation of the phrase "blancos del metodo". A literal translation of "method blanks" to me sounds terrible, very stilted and contrived. Please see this context and give me your informed opinion. (This comes from Ecuador, by the way.) Many thanks in advance.

El propósito de incluir el Registro de Control y Garantía de Calidad cuando se entrega un
reporte de ensayos de laboratorio es para:
(...)
ii) Demostrar que el laboratorio mantuvo control estadístico de los análisis durante cada
uno de ellos. Estos procedimientos de Control de Calidad deben de incluir, por lo
menos, el uso de muestras especiales que se conocen como “muestras de control” y
**“blancos del método.” **

method blanks

Hello Karen, you were right, even when it sounds terrible.

In quality control assays, several blanks are needed to control external sources of contamination: a field blank, an equipment blank, a method blank, etc.

Here you have a fact sheet from EPA:

Here is another guidefrom the Wisconsin Department of Natural Resources:

Example sentence:

Method Blank: A blank prepared to represent the matrix as closely as possible.

...special samples which, in the test method, are known as control samples and blanks.

Hope this is something you can use.

You may want to use "controls" instead of "control samples".
