Au d\u00e9part, pour identifier les fuites importantes, utilisez un d\u00e9tecteur de fuites de gaz \u00e9lectronique aux points de pression (par exemple, l\u2019injecteur). Apr\u00e8s avoir \u00e9limin\u00e9 les fuites importantes qui pourraient endommager le filament, utilisez votre spectrom\u00e8tre de masse pour d\u00e9tecter la pr\u00e9sence d\u2019une fuite plus petite. Votre spectrom\u00e8tre de masse est un moyen efficace d\u2019identifier une fuite plus petite mais il ne permet pas de la localiser. Aux endroits o\u00f9 le vide a une forte influence, comme au niveau du connecteur entre la colonne restrictive et la colonne analytique, ou le raccord entre la colonne et le spectrom\u00e8tre de masse, nous recommandons d\u2019utiliser une “bombe \u00e0 air” (couramment utilis\u00e9e pour d\u00e9poussi\u00e9rer les claviers). La bombe \u00e0 air contient habituellement un compos\u00e9 halog\u00e9n\u00e9 que le spectrom\u00e8tre de masse peut suivre en temps r\u00e9el. De br\u00e8ves pulv\u00e9risations d\u2019air \u00e0 proximit\u00e9 des connexions cr\u00e9ent une augmentation de l\u2019ion m\/z correspondant au compos\u00e9 halog\u00e9n\u00e9, ce qui indique la pr\u00e9sence et l\u2019emplacement de la fuite.<\/p>\n","protected":false},"excerpt":{"rendered":"
