Large collection of accessories for automization and specific measurements. Big collection of ESR glassware
autosampling for liquids, powders and solid samples
Why buy an expensive mammoth sized ESR spectrometer when the benchtop MS5000 can do the same job?
This is accomplished by:
The use of modern electronic design minimizes the entire electronics to the size of a small notebook. Combination of high frequency circuits for space application enable extraordinary signal to noise ratios.
The use of a compact high performance rectangular resonator. This allows for a small magnet air gap and consequently a very compact magnet design. However, sample size up to 8 mm is standard.
Very compact mechanical design - the entire electronics is based on a few tiny high- tech PCB boards including microwave integrated circuits. There is almost no wiring. This results in high reliability, easy maintenance and service and a very efficient assembly during production, allowing for a high cost effectiveness.
The system has extensive automatic self- test and calibration facilities
All accessories such as Autosampler, Sample cooling or heating systems, Goniometer and others are connected by a proprietary bus system and can be easily attached to the main ESR system at any time
Universal power supply 110 V to 260 V, 50/60 Hz AC which meets world wide safety and EMV standards
Maximum power consumption at highest magnetic field is 200 W and the stand-by power consumption between measurements is very low.
The spectrometer is completely air- cooled, no water cooling is required
Modern software (ESRStudio) for spectrometer Operation and Data Evaluation
ESR- signal intensities according to the individual saturation behavior of ESR- lines. This greatly helps to identify individual lines in complex ESR- spectra. At a given microwave power and temperature, heavily saturated lines exhibit large signals whereas unsaturated lines do not show up at all.
This enables the detection of extremely weak lines as well as extremely strong lines in the same spectrum. No “amplification factor” or similar needs to be set before the measurement.
