In thermal conductivity analysers, a Wheatstone Bridge Circuit measures the imbalance caused by passing gas over detector filaments, using half of the cells for the fumigant air mixture and the other half for air as a control. This analyser, in a portable form, is commonly used to check for methyl bromide in ship holds, but it can also be calibrated for other gases. It will not differentiate between fumigants if mixtures are used.  1, record 2, English, - thermal%20conductivity%20analyser

Dans ce genre d'appareil, on utilise un circuit à pont de Wheatstone pour mesurer le déséquilibre provoqué par le passage d'un gaz au-dessus des filaments détecteurs. La moitié des cellules sert à l'analyse du mélange fumigant/air; l'autre moitié sert aux mesures témoins avec de l'air uniquement. On utilise couramment des modèles portatifs pour mesurer les concentrations de bromure de méthyle dans les cales de navire, mais on peut aussi étalonner les analyseurs en fonction d'autres gaz. En pratique, les analyseurs à conductivité thermique conviennent mal pour l'analyse de mélanges de fumigants.  1, record 2, French, - analyseur%20de%20gaz%20%C3%A0%20conductivit%C3%A9%20thermique

A device for the extremely sensitive measurement of the refractive index of liquids; used as a detector in liquid chromatography.  2, record 3, English, - differential%20refractometer

Record number: 3, Textual support number: 1 CONT

The most universal continuous detector for liquid chromatography is the differential refractometer. This detector is universal only to the extent that one can select an eluent the refractive index of which differs from that of the solutes. Pure eluent flows through one cell of the detector while column effluent flows through the other cell. When a solute with a refractive index different from that of the solvent enters the detector, an imbalance occurs, which is transmitted to the recorder. The differential refractometers are relatively insensitive to trace and minor components, and detector stability is greatly affected by small temperature and flow fluctuations, thus requiring very good flow and temperature controls.  3, record 3, English, - differential%20refractometer

Le réfractomètre différentiel mesure en continu la différence d'indice de réfraction entre la phase mobile et l'effluent de la colonne chromatographique. La limite de détection dépend à la fois de la nature du soluté et de celle de la phase éluante.  2, record 3, French, - r%C3%A9fractom%C3%A8tre%20diff%C3%A9rentiel
