400 spectrometer

Manufactured by Brucker

The 400 spectrometer is a laboratory instrument designed to measure the absorption or emission spectra of various samples. It is used to analyze the composition and properties of materials by detecting the interaction between light and the sample. The core function of the 400 spectrometer is to provide precise spectral data for research, analytical, and quality control applications.

¹H NMR spectra were recorded on a Brucker 400 spectrometer in CDCl₃. Residual CHCl₃ (7.26 ppm) was used as internal reference. ¹³C NMR spectra were recorded at 100.6 MHz in CDCl₃. Residual CHCl₃ (77.0 ppm) was used as internal reference. In situ FTIR spectra were collected on a Mettler Toledo React IR ic10, which was equipped with a diamond ATR probe, using an ic IR analysis system. The probe was placed into the absorption mixture. Spectra were collected in situ during CO₂ absorption, while the mixture was stirred continuously using a magnetic stir bar. ESI-MS spectra were recorded on a Thermo Finnigan LCQ Advantage spectrometer in ESI mode at a spray voltage of 4.8 kV.

The organic reagents and solvents were purchased from Sigma-Aldrich and used directly without further purification. All solid reagents were dried under a high vacuum line prior to use. Air sensitive reactions were carried out under nitrogen. Analytical TLC plates pre-coated with silica gel F₂₅₄ (Dynamic Adsorbents) were used for monitoring reactions and visualized by UV light. Flash column chromatography was performed using silica gel (32–63 μm). All ¹H, ¹³C and ³¹P NMR spectra were recorded on a Brucker 400 spectrometer. Chemical shift values are in ppm. ¹³C NMR signals were determined by using APT technique. High-resolution MS data were achieved by ESI mass spectrometry at University at Albany, SUNY.

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.
