X band emx spectrometer

Manufactured by Oxford Instruments
Visit Supplier

The X-Band EMX spectrometer is a laboratory instrument designed for electron paramagnetic resonance (EPR) spectroscopy. It operates at X-band microwave frequencies, which are commonly used for the analysis of paramagnetic samples. The core function of the X-Band EMX spectrometer is to detect and characterize unpaired electrons in materials, providing information about the structure and properties of the sample.

Electron paramagnetic resonance spectra were measured on a Bruker X-Band EMX spectrometer equipped with an Oxford Instruments 3 S3 liquid helium cryostat. EPR spectra were obtained on frozen solutions using 20 mW microwave power and 100 kHz field modulation with the amplitude set to 1 G. All samples were measured at 12 K.

Spectroscopic Characterization of Molecular Compounds

Check if the same lab product or an alternative is used in the 5 most similar protocols
All UV-Vis spectra were recorded using an Analytik Jena Specord S600 spectrometer in quartz cuvettes. Proton NMR spectra were recorded on a Varian MR 400 MHz instrument, or a Varian VNMRS 500 MHz spectrometer at room temperature. All NMR spectra were referenced to internal solvent peaks or TMS.
Electron paramagnetic resonance (EPR) spectra were recorded on a Bruker X-band EMX spectrometer equipped with an Oxford Instruments liquid nitrogen cryostat. EPR spectra were obtained on frozen solution samples (~1 mM) in a 1:2 mixture of glycerol and water at 110 K, using 20 mW microwave power and 100 kHz field modulation with the amplitude set to 1 G. EPR spectra were fitted to determine the g-values using the program SpinCount (by Prof. M. P. Hendrich, Carnegie Mellon University). Mass spectra were collected using an Agilent 6230 time-of-flight (TOF) LC-MS system in positive ion mode, with reference mass ions of m/z = 922 and m/z = 121.

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.
