Questa tecnica spettroscopica dà informazioni sui gruppi funzionali presenti nella molecola attraverso la formazione di segnali. In realtà nello spettro IR sono presenti due “tipi” di segnali FTIR can generate an infrared spectral scan of samples that absorb infrared light. Scope: Standards include: ASTM E168, E1252. If the material does not absorb infrared light a spectral scan cannot be obtained. Example: metals do not absorb infrared light.

Attenuated total reflection (ATR) is a method that allows the direct measurement of samples for FTIR. ATR method involves pressing the sample against a high-refractive-index prism and measuring the infrared spectrum using infrared light that is totally internally reflected in the prism. FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. In infrared spectroscopy, amples as small as 50 µm using ATR•S •Fibers, pellets, paper, powdered samples •Plug and play design for quick analysis BR50555_E 05/13M Africa +27 11 822 4120 ATR protocol (JASCO FTIR-4100) 1.

The most recent FTIR technique for soil analysis is attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), unique in that it offers in situ study of soil minerals, SOM, bacteria, and other samples in the presence of water.

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.

If you have 2013-04-01 · ATR is one of the most common, as its robustness makes it suitable for the widest range of applications. The Agilent diamond ATR accessory for the Agilent Cary 630 FTIR is a single bounce ATR speciﬁ cally designed to optimize the energy throughput, ensuring you achieve the highest quality spectra. Traditional diamond ATRs Pathlengths from 6 µm to 1mm.

ATR is one of the most used sampling technologies for FTIR Spectroscopy. The reason for the ubiquitous use of ATR is that it enables solids and liquid samples to be analyzed neat – simplifying the measurement of virtually all substances. Attenuated Total Reflection (ATR) sampling revolutionized FTIR spectroscopy, with its simplicity of sample handling and near-universal applicability. This webinar will introduce the theory and basic use, ideas for ATR, and will show many examples.
