Device for qualitative and/or quantative analysis of a sample

摘要: Disclosed is a device for qualitative and quantitative in-vitro or in-vivo analysis of sample by means ATC (Attenuated Total Reflectance) while utilizing at least one radiation source, an ATR element as well detector unit. The present invention distinguished the combination following features: source generating primary beam aimed element, impinging on angle α, which larger than critical total reflectance α T interface between optically dense medium less one; to-be-analyzed whose layer near surface interacts with can be disposed side unit corresponding to incidence said in detects emitted from element.
