Bruker Epr Software

The Bruker EMXplus Spectrometer System uses EPR (Electron Paramagnetic Resonance) which is a very useful and powerful technique for studying samples that are paramagnetic (i.e. Have unpaired electrons). Applications of EPR include: • Kinetics of radical reactions • Redox processes • Metal ions • Defects in crystals • Polymer properties • Effects of ionizing radiation • Spin labeling and spin trapping • Antioxidants • Enzyme and carcinogenic reactions • and many more Spectrometer Features: • Microwave Frequency Range: CW X-Band (9 - 9.8GHz) • X-Band Solid State Ultra Low Noise Microwave Bridge • Max leveled source output: 200 mW • Max.

• • • • Bruker EMX basic operation System Startup • Sign in in the log book. • Make sure the chilled water is on. • Turn on the heat exchanger.

• Turn on the power supply (Do Not Turn On The Magnet!) • Turn on the EMX console. • If you want to use the Gauss Meter start it up by double clicking the bootp desktop icon. Wait for a response indicating the bootp process has completed. Stow the bootp window.

• Start the Win-EPR Acquisition software. The icon is on the desktop. • Turn on the magnet. Cavity Tuning • Click on the icon. The Microwave Bridge Control window will pop up. • The bridge will be in the standby mode. Select Tune and set the microwave attenuation to 25 dB.

• Wait a few seconds to allow the frequency to set. Adjust the frequency to locate the cavity dip and set it so that the frequency marker is at the bottom of the dip.

This should be the point where the dip is the deepest. • Select operate. Set the microwave attenuation to 40 dB. The AFC meter should be in the green at this point. If not adjust the frequency until it is.

If the frequency is close you can use the fine tune button. • Adjust the diode bias so that the meter is centered in the green.

• Lower the microwave attenuation by 10 dB. If the diode current meter deflects all the way to one side or the other increase the attenuation in 1 dB increments until the meter is on scale. • Adjust the iris up or down so that the diode current meter is centered. Make sure the AFC stays in the green throughout the process. Battery Optimizer Crack - Torrent. If not adjust the frequency to bring it back. • Repeat steps 5 and 6 until you have reached 10 dB and the diode meter is centered.

• Adjust the phase so as to maximize the diode current. Use the iris to bring the diode current back to the center.

• Set the microwave attenuation back to 40 dB. Make sure the AFC is still in the green. If the diode current has moved off center repeat steps 5 - 10. Recording a Spectrum • Click the (Interactive) icon.

The Interactive window will pop up. • If you have changed cavities make sure to change the calibration file. You can do this by clicking then select change file.

• Set the desired center field, sweep width, modulation amplitude, modulation frequency, receiver gain, time constant, conversion time and microwave attenuation. • Open a spectrum window by clicking the icon.

• In the interactive window click on. The mouse cursor will change to a P.

Soal Spa Polines Semarang more. Move the cursor into the new spectrum window and click. The parameters will be transferred and the cursor will change back to an arrow. • Alternatively you can open an existing file which will load its parameters.

Then drag the spectrum into a new spectrum window. This is the recommended procedure as any changes made to the parameters in the opened file will be over written if a save is executed.
