Abstract

Pendant l'affichage de résultats quantitatifs consolidé pour de multiples échantillons et de multiples constituants, une unité de traitement d'affichage de table (26) affiche, sur un écran d'affichage, une table d'informations numériques dans laquelle des valeurs quantitatives, ou analogue, sont disposées dans les cellules d'une table à deux dimensions dans laquelle des informations d'échantillon et des informations de constituant sont fournies dans la direction de rangée et la direction de colonne conjointement avec une table de traçage de graphes dans laquelle un chromatogramme de masse réduite est disposé à l'intérieur de la table dans des cellules qui ont la même disposition de rangées et de colonnes en tant que table d'informations numériques. Lorsqu'une condition de filtre est réglée pour déterminer des combinaisons de constituant et d'échantillon montrant des valeurs quantitatives dépassant une valeur de référence, une unité d'évaluation de filtrage (25) évalue les valeurs quantitatives de chaque cellule. Dans la table de traçage de graphes, l'unité de traitement d'affichage de table (26) affiche des chromatogrammes correspondant à des valeurs quantitatives éliminées par le filtrage dans une couleur plus claire (dispositif d'affichage semi-transparent) que d'autres chromatogrammes. Il en résulte que, tandis que les relations de rangées et de colonnes dans la table de traçage de graphes ne changent pas en tant que résultat du filtrage, il est non seulement plus facile de comprendre visuellement quels chromatogrammes sont restés après le filtrage mais aussi de comprendre des combinaisons de constituant et d'échantillon.
