En ICPMS [spectrométrie de masse à plasma à couplage inductif], les effets de matrice commencent à se manifester lorsque les concentrations des espèces concomitantes dépasse 500 à 1000 μg/ml [microgrammes par millilitre]. Habituellement, ces effets entraînent une diminution du signal de l'analyte, bien que, dans certains cas particuliers, on puisse observer une augmentation. Les effets de matrice sont tout à fait généraux en ce sens qu'ils apparaissent lorsque la concentration de presque tous les éléments concomitants est élevée. 2, record 1, French, - effet%20de%20matrice

Chemical matrix effects occur when the presence of one element affects the emission characteristics of another element. This can complicate calibration of the technique and hence the ability to obtain quantitative results. These effects can be compensated for in the analysis if the concentration and effect of the interfering element(s) are known. ... An example of a chemical matrix effect is the reduction in emission intensity of an ionized species ... upon a significant increase in the concentration of an easily ionizable species in the matrix. 2, record 2, English, - chemical%20matrix%20effect

Method devised by Brown which is particularly useful when, owing to its chemical nature, insolubilization of an enzyme cannot be achieved by glutaraldehyde crosslinking alone. To eliminate the loss of enzyme activity due to diffusion effects caused by crosslinking, reactions enzymes, at low concentrations, are crosslinked via glutaraldehyde to a nonenzymic protein which is rich in L-lysine residues (such as bovine serum albumin), and the resultant immobilized enzyme can be insolubilized by gel entrapment methods. 2, record 6, English, - co%2Dcrosslinking

Outre que l'irradiation augmentant les mobilités atomiques, via les sursaturations de défauts ponctuels, peut accélérer les cinétiques de ségrégation d’équilibre sur les différents puits, joints de grains inclus, elle peut également conduire à des ségrégations(ou appauvrissements) hors d’équilibre. Dans ce cas, on parle de ségrégation induite par l'irradiation. Son origine est purement cinétique. Elle provient de couplages positifs ou négatifs entre les flux de défauts allant s’éliminer sur les puits et les flux de soluté. Ce phénomène se produit soit si un élément d’alliage possède un coefficient de diffusion différent de la matrice(effet Kirkendall inverse) ou si un soluté en faible concentration interagit fortement avec les défauts ponctuels. 1, record 8, French, - effet%20Kirkendall%20inverse
