This webinar will introduce the theory and basic use, ideas for ATR, and will show many examples. Register for this on-demand webinar and learn more. ATR: Watch and learn with this video series FT-IR Spectroscopy Attenuated Total Reflectance (ATR) Attenuated total reflection (ATR) is a sampling technique used in conjunction with infrared spectroscopy which enables samples to be examined directly in the solid or liquid state without further preparation. Light undergoes multiple internal reflections in the crystal of high refractive index, shown in yellow. Attenuated total reflection (ATR) is a method that allows the direct measurement of samples for FTIR.

The unique design of this ATR accessory allows for the direct measurement of protein powders, gels, FTIR-FC 小型衰減全反射紅外光譜儀 (ATR)，是瑞士 Arcoptix 專業紅外光譜儀器製造商，在2017年全新推出的一部劃時代產品。 FTIR-FC 是目前世界上最新先進、體積最小的傅式轉換中紅外光譜儀，它裝置了光纖式的 ATR 探頭，可更方便接觸各種樣品表面，或者將 ATR 裝置在更嚴苛的環境中，而不影響正常紅外光譜量測。 ATR spectra are somewhat different than those produced by transmission sampling techniques – both in relative intensity of the absorbance bands and also the position of the bands. To assist with calibrating your ATR/FTIR system, PIKE Technologies offers an ATR Reference Standard. The ATR Reference Standard is available 用ftir测量薄膜的特性，实验室用的是atr-ftir模块，博后说薄膜厚度得700nm以上。但是我看很多文献ftir测量(没用atr模块)都报道了厚度在200nm以内的结果。请问ftir与atr-ftir的区别在哪里，在装置设置上又有哪些不同。实在是不想用那么厚的膜啊。谢谢！ The ATR technique (attenuated total reflection and internal reflection) is attractive to a wide range of application (e.g., films, rubber, polymers and liquid samples) because sample pretreatment is unnecessary to obtain information from the surface of the sample. This advantage was further utilized through the incorporation of the ATR objective lens in a microscope and the single-reflection FTIR Spectrometers.
