Disinfection process, mainly with chlorine, to prevent microbiological contamination of water can lead to the formation of hazardous disinfection by-products(DBPs) due to the reaction of chlorine with natural organic matter(NOM) present in the water.... Beyond specific health based thresholds, DBPs can represent a public health issue due to the potential chronic risk of adverse effects on human health(e. g., cancer, reproductive and developmental effects) and the high prevalence of exposure. Thus, DBPs constitute an important concern for water systems, especially systems supplied by surface waters.... Recently, a technique known as differential UV [ultraviolet] absorbance(DUVA) has been developed that could provide a sensitive and highly specific indicator for DBP formation resulting from chlorination. 2, record 1, English, - differential%20UV%20absorbance

[Des auteurs] ont publié un rapport sur l'utilisation de la méthode du différentiel d'absorbance UV [ultraviolet] (DAUV) pour estimer la formation des SPD [sous-produits de désinfection]. Cette méthode est basée sur le principe que la matière organique absorbe la lumière. Lorsque le chlore entre en contact avec la matière organique, celle-ci s'oxyde, ce qui entraine la formation de SPD, mais aussi une diminution de la capacité de la matière organique à absorber la lumière (absorbance). [...] Les auteurs soulignent que cette méthode peut s'avérer un outil fort utile pour le suivi des SPD dans les réseaux de distribution et dans les stations de traitement, en permettant de sauver temps et argent pour les analyses. 2, record 1, French, - diff%C3%A9rentiel%20d%27absorbance%20UV

Since citrate detergents are likely to become progressively more prominent, an assay method for citrates in such preparations was needed. An enzymic method was devised by Taraborelly and Upton in Pfizer's quality control laboratory. A coupled sequence of reactions is used to give a fast, simple, and specific assay method. These reactions are shown in Equations 1 and 2.... NADH is destroyed in the "indicator reaction" of this coupled sequence. This destruction is measured by the decrease in absorption at 340 nanometers and the citrate concentration is easily calculated. 1, record 2, English, - indicator%20reaction

Les réactions indicatrices sont nécessaires lorsque le substrat dosé ou le produit de la transformation ne possèdent pas de propriétés spectrophotométriques particulières. [...] Exemple : lorsque l'enzyme E, dont on mesure l'activité, n'est pas une déshydrogénase à NAD+ ou NADP+, et que ni le substrat S, ni le produit P ne possèdent de propriétés spectrales particulières, on couple la première réaction à une deuxième, catalysée par une déshydrogénase dont P est le substrat.

Erreur de précession. Les forces de friction présentes dans le système gyroscopique engendrent la précession. Cette précession occasionne un «glissement» ou une «dérive» d'environ 3 degrés dans la lecture de l'instrument et ce, à toutes les 15 minutes. Le gyroscope est aussi sujet à la précession apparente. L'inertie gyroscopique garde le gyroscope fixe dans l'espace de sorte qu'il ne bouge pas par rapport à l'espace. Cependant, la terre qui tourne en dessous du gyroscope donne à ce dernier un mouvement apparent par rapport à la terre. La rotation de la terre cause une dérive apparente, ou précession, qui varie avec la latitude [...] L'erreur de précession, à la fois mécanique et apparente, doit être corrigée à intervalles réguliers, c.-à-d. toutes les 15 minutes. 2, record 5, French, - correction%20de%20l%27erreur%20de%20pr%C3%A9cession

The course of the reaction is monitored radiochemically by adding a radioactive indicator which may be precipitated, or dissoved, at the equivalence-point, thus changing the radioactivity of the solution phase. A plot is made of instrumental response against titrant added. End-points are generally located by extrapolation at changes in slope in the titration curve.(In some instances the titratable solute or the titrant may be radioactive, in which case no added indicator may be required. 1, record 8, English, - radiometric%20end%2Dpoint

Le déroulement de la réaction est suivi par une méthode radiochimique après addition d'un indicateur radioactif qui peut, soit précipiter, soit se redissoudre au point d'équivalence, modifiant ainsi la radioactivité de la solution. On représente la variation de la réponse de l'instrument de mesure en fonction de la quantité de réactif titrant ajouté. Le point de fin de titrage est généralement obtenu par extrapolation au changement de pente (dans certains cas, le soluté titré ou le réactif titrant peuvent être radioactifs; il n'est alors pas nécessaire d'ajouter un indicateur). 1, record 8, French, - d%C3%A9tection%20radiom%C3%A9trique
