Using attenuated total reflectance (ATR), we … An FTIR spectrometer with an ATR accessory is simple to use and relatively inexpensive. Further, the small form factor of the Nicolet iS5 Spectrometer allows it to be moved close to where microplastics are to be collected and studied. This can be an advantage in environmental FTIR / ATR | Harrick Scientific Products Inc. ATR-FTIR Kretschmann and EIS set-up was therefore further applied to systems where a surface pre-treatment had been applied to the metal prior to organic coating.

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.

Laboratory studies on stripping at bitumen/substrate interfaces

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. Attenuated-total-reflectance (ATR) is a sampling mode which enhances the Fourier Transformed Infrared Spectroscopy (FTIR) signal obtained from sample surfaces, increasing sensitivity and allowing efficient measurements with minimal sample preparation. Like standard FTIR measurements, ATR-FTIR is used for chemical qualification of a sample from Attenuated total reflectance (ATR) is one accessory of FTIR spectrophotometer to measure surface properties of solid or thin film samples rather than their bulk properties.
