ENinternal standard, IS 
substance which is similar in the chemical behaviour (chemical structure – polarity) and analytical response to a certain target analyte

Note 1 to entry: A defined volume of the internal standard solution is added to both the sample and calibration solutions such that they both contain an identical concentration.

FRétalon interne, IS  
substance dont le comportement chimique (structure et polarité chimiques) et la réponse analytique sont similaires à ceux d’un analyte cible

Note 1 à l’article: Un volume défini de solution d’étalon interne est ajouté à l’échantillon et aux solutions d’étalonnage de sorte que leur concentration soit identique.
