Abrégé
(EN)
Apparatus for analysing a liquid sample (194) comprises beam generating means (1) for generating electromagnetic radiation, detector means (8) for detecting electromagnetic radiation from the beam generating means after the radiation has interacted with the sample, and sample retaining means (10) for releasably retaining sample in the path of the beam. The sample retaining means comprises a hydrophobic surface (for example, a coating on a plate 118) on which the sample is, in use, supported. There is also disclosed a method of performing photometric or spectrophotometric analysis of a liquid sample by sandwiching samples between two opposed hydrophobic support surfaces, passing a beam of electromagnetic radiation through one of the surfaces and then through the sample, and analysing the beam after it has passed through the sample.

L'invention concerne un appareil permettant l'analyse d'un échantillon liquide (194) qui comprend un moyen de génération de faisceau (1) pour générer un rayonnement électromagnétique, un moyen de détection (8) pour détecter un rayonnement électromagnétique provenant du moyen de génération de faisceau une fois que le rayonnement a interagi avec l'échantillon, et un moyen de maintien d'échantillon (10) pour maintenir l'échantillon de manière amovible sur la trajectoire du faisceau. Le moyen de maintien d'échantillon comprend une surface hydrophobe (par exemple, un revêtement sur une plaque 118) sur laquelle l'échantillon est supporté en cours de fonctionnement. L'invention concerne également un procédé de réalisation d'une analyse photométrique ou spectrophotométrique d'un échantillon liquide en intercalant les échantillons entre deux surfaces supports hydrophobes opposées, en faisant passer un faisceau de rayonnement électromagnétique à travers l'une des surfaces et ensuite à travers l'échantillon, et en analysant le faisceau une fois qu'il a traversé l'échantillon.
