Definitions
- the prior art TOC shown in Figure 1 comprises a carrier gas supply 1 and a gas flow control unit 2 which controls the flow rate of carrier gas to a furnace 3.
- the sample to be measured is held in syringe 4.
- the outlet line 5 from the furnace is also connected to the IC reaction vessel.
- sample introduction valve described may also be used in other laboratory analysis or sample introduction applications where, for example, a septum or injection valve would currently be employed: for example in chromatogr phy.

Abstract
Analyseur permettant de mesurer le carbone présent dans un échantillon, comprenant un fourneau (3), un vase de réaction (7), un déshumidificateur (8), un détecteur (10) ainsi qu'un moyen (1) permettant de faire circuler l'échantillon dans un gaz vecteur à travers le fourneau et/ou le vase du réacteur en vue d'obtenir du dioxyde de carbone, lequel est acheminé par l'intermédiaire de l'humidificateur vers le détecteur. L'invention est caractérisée en ce qu'une unité (2) de commande de circulation du gaz vecteur est située en aval du fourneau. L'analyseur peut comprendre également un moyen (20) d'alimentation supplémentaire en gaz vecteur du dioxyde de carbone circulant dans le détecteur, l'alimentation supplémentaire en gaz vecteur ayant pour effet de diluer le dioxyde de carbone.
