Manufactured by PerkinElmer
Visit Supplier
Sourced in United States

The Spotlight 400 ATR-FTIR spectrometer is a Fourier Transform Infrared (FTIR) spectroscopy instrument designed for materials analysis. It utilizes Attenuated Total Reflection (ATR) to obtain infrared spectra of solid, liquid, or powder samples. The spectrometer measures the absorption of infrared radiation by the sample to provide information about its chemical composition and molecular structure.

The freshly prepared nanoparticle dispersions were freeze-dried and then examined by a Spotlight 400 ATR-FTIR spectrometer (PerkinElmer Company, USA) (Xu, Yang et al., 2022 (link)). The scanning number was 16. The wavenumber range was 4000–600 cm−1. The scanning resolution was 4 cm−1. The PeakFit v4.12 software (SeaSolve software Inc., Framingham, CA, USA) was used to analyze the secondary structure percentages of the nanoparticles by fitting the ATR-FTIR spectra at 1700–1600 cm−1.

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.
