A disposable all purpose micro sample holder comprised of a thin rigid plate- shaped frame (1), substantially opaque to infrared light, having a bore (2) extending therethrough in or over which is mounted an optical window (4) made of a material substantially transparent to infrared light. An optional flexible film (6) is sized, shaped and affixed to the upper surface of the frame to completely cover the bore in the frame. The film is substantially transparent to the frequencies of the infrared light to be used. A sample (25) is placed on optical window over the bore and beneath the film. For powder or solid samples, two sample holders, without the film, are releasably clamped together.

La présente invention concerne un support jetable de micro-échantillons pour tous usages. Il comprend un cadre (1) mince et rigide, en forme de plaque, sensiblement opaque à la lumière infrarouge, présentant un trou (2) qui le traverse, et dans lequel ou au-dessus duquel est montée une fenêtre optique (4) faite d'une matière sensiblement transparente à la lumière infrarouge. Un film optique souple (6) a une taille et une forme adaptées à la surface supérieure du cadre, sur laquelle est placé ledit film pour couvrir entièrement le trou du cadre. Le film est sensiblement transparent aux fréquences de la lumière infrarouge à utiliser. Un échantillon (25) est placé sur la fenêtre optique, au-dessus du trou et au-dessous du film. Pour les échantillons pulvérulents ou solides, deux porte-échantillons, sans le film, sont montés ensemble de façon amovible.
