A typical slow analyser might have a response time of 1-2 seconds. The Cambustion HFR fast response FID analyzers use conventional detection principles and a unique patented sampling system to give millisecond response times.
In deze detector brandt een waterstofvlammetje dat tussen twee elektroden geplaatst is. De componenten die de kolom verlaten worden hierdoorheen geleid. Ze verbranden dan, waarbij ionen gevormd worden. Deze ionen zorgen ervoor dat er een klein elektrische stroompje tussen de elektroden gaat … Meer weergeven Een vlamionisatiedetector (Engelse afkorting: FID, Flame Ionization Detector) is een detector die wordt gebruikt in de gaschromatografie.
