Atr unit

Manufactured by PerkinElmer
Visit Supplier
Sourced in United States

The ATR unit is a laboratory instrument used for spectroscopic analysis. It functions by directing infrared radiation through a specialized crystal, where the sample is placed. The reflected radiation is then detected and analyzed, providing information about the chemical composition of the sample.

ATR-FTIR Analysis of Ileum and Colon Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
Ileum and colon samples of all animals were compressed on the Zn/Se crystal of the ATR unit (PerkinElmer) without any pretreatment and examined with an ATR‐FTIR spectrometer (PerkinElmer) at a resolution of 4 cm−1 and a scan number of 32. The spectra were obtained with the Spectrum One (PerkinElmer) software in the wavelength range of 4000–650 cm−1.16

FTIR Analysis of Acetylated and Untreated Cellulose Nanofibers

Check if the same lab product or an alternative is used in the 5 most similar protocols
Powder of acetylated and untreated CNF was scanned in absorbance mode with a mid-infrared spectrometer using an ATR-unit (PerkinElmer Inc., USA). Fifty scans were recorded at a resolution of 4 cm -1 within the range of 4000-650 cm -1 . The contact surface had a dimension of 2 mm 2 , and a pressure of 0.1 Nm was applied. The spectra were normalized to the intensity of the band at 2890 cm -1 corresponding to C-H stretching, where no shift is expected due to acetylation (Ernest-Saunders et al. 2014) .

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
