400 and 100 mhz spectrometer

Manufactured by Bruker

Sourced in China

The 400 and 100 MHz spectrometers are analytical instruments used for nuclear magnetic resonance (NMR) spectroscopy. The 400 MHz spectrometer provides higher magnetic field strength, while the 100 MHz spectrometer offers a lower field strength. These spectrometers are designed to analyze the chemical composition and structure of various substances through the detection and interpretation of the magnetic properties of atomic nuclei.

Grade quality solvents and reagents were purchased commercially. Highly purified compound such as 2-aminothiazole and salicylaldehyde was purchased from Hi-media. The ¹H and ¹³C NMR spectra were recorded from Bruker 400 and 100 MHz spectrometer using DMSO-d₆ solvent and Trimethylsilane (TMS) as an internal standard. Absorption studies were carried out using Shimadzu UV-240 spectrophotometer. The fluorescence study was recorded on Jasco FP-8200 spectrofluorometer. The absorption and emission spectra were recorded at 24 ± 1 °C.

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.
