application

Relaxation time measurement

Measuring electronic relaxation rate, T1 and T2, can understand the dynamics and structure of the material.T1 provides relevant molecular collision, coupling of excited state, of the distance between the center of the lattice vibration and magnetic information.T2 provides related molecular rolling, internal rotation and two very rich information and the distance of the interaction.

SECSY and EXSY

Spin echo correlation spectrum (SECSY) and exchange (EXSY) is a two-dimensional technology.The location of the cross peak in two dimensional spectrum was used to correlate spectral peak, cross peak amplitude of the exchange rate to carry information.The experiments are E580 standard function of the spectrometer by predefined PulseSPEL program support.

Laser trigger experiment

External events, such as laser flash, can be used to produce the paramagnetic state.For this type of experiment, the instrument can be triggered from outside, or instrument can send a trigger to activate external equipment.External events, microwave pulse, and established a precise synchronization between data acquisition.Any pulse EPR experiments can be combined with external trigger function running.

Pulse ELDOR and DEER

- electronic double resonance (ELDOR) and double - electronic resonance (DEER) is the abbreviation of the same technology.Electron spin can be measured by this technique, the bipolar interaction between.This information directly into the distance between the electron spin.Cover the distance range of 10 to 80 esther.In recent years, the site directed the combination of spin labeling and DEER become one of the most popular tools in the study of structural protein.

ESEEM and 2 d - HYSCORE

Electron spin echo envelope modulation (ESEEM) is a measurement of electron spin and super fine interaction between nuclear spin near one of the most popular technology (HFI) parameters.Through the analysis of ESEEM signal, can get the electron spin density distribution, distance and bond Angle of detailed information.2 d - HYSCORE is also a kind of technology based on ESEEM effect, is the preferred method of frozen solution and powder.All ESEEM type experiment are E580 standard function, and by Xepr special collection and processing tool support.

Pulse is ENDOR ESEEM complementary technology, combined with MW and RF pulse.Its measuring superfine interaction (HFI), in order to provide the electron spin density, distance and the bonding Angle of detailed information.It is good at measuring extremely short or transition metal nuclear ultrafine strong interaction.

And X band (9.5 GHz, 22 hours measure time) compared to Q band (33.5 GHz, 25 minutes to measure time) of DEER experiment greatly increased sensitivity.

Technical parameters

Pulse EPR has become a mature paramagnetic material research tools.From the beginning, passed in 1987 launched the ESP for 380 pulse EPR instrument set a milestone for commercial use.The next milestone is ELEXSYS E580 subsequent models, as well as new high speed digital equipment PatternJet and SpecJet.This is the first time in human history can not restricted by hardware, at the rate of the spin relaxation to average FID and echo.

The attachment

Another cornerstone - probe spectrometer, is always the key point of the research and development for many years.This is the legendary Flexline probe series.

ELEXSYS E 580 FT/the CW x-band spectrometer is also more extended frequency of the platform.On the basis of x-band spectrometer for W band (680) E, Q band (SuperQ - FT), S band, (SuperS - FT) and l-band frequency conversion (SuperL - FT).The unique design concept of x-band all features can be found in the double frequency band is conerted to additional spectrometer.

software

Xepr for experiment design and data handling

Is addicted flexibility and ease of use are the attributes of the Xepr software. Been you are 'dealing with a simple echo decay or a complicated multiple - pulse 2 d experiment, the graphical user interface of Xepr ensures easy instrument control, experiment definition and execution. Numerous will processing tools, the display "capabilities and data representations open up new dimensions in the data analysis as well.
