Electron Paramagnetic Resonance SPECTROMETER         ELEMENTAL ANALYSIS
The EPR spectrometer, Model MiniScope MS 300 (X-band and 9.3 - 9.55 GHz) is designed for easy operation, compact, PC-controlled, high performance devices for all laboratories.
Samples from liquids to solids can be measured at room temperature - 196 C for liquid nitrogen or at temperatures between - 170 up to + 200 C.
By the scan range of up to 400 mT and optional 550 mT with free radicals paramagnetic transition metal ions can be detected. The MiniScope can be applied from research up to routine measurements.
The MINISCOPE MS 300 consists of the following items:
- Spectrometer with measurement sensitivity 8*10Description: http://www.magnettech.de/images/hoch9.gif Spins/0,1mT.
- Control software.
- Analysis software for data calculation.
- Multiplot software for data presentation.
- Guidance tube F 120/1.5 for capillaries.
- 250 Pieces 50 l capillaries.
- Sealing kit for capillaries.
- Connector for vessels flushing the resonator with dry nitrogen.
Irradiation Window:
Allows irradiation of samples in the resonator during the measurement, using a parallel beam.
It is an option to insert a standard sample into the resonator.
Ultra-fast Automatic Frequency Control (AFC):
The boiling of liquid nitrogen in the fixed temperature dewar can lead to spikes on the spectrum. The ultra-fast AFC prevents this by keeping the measurement conditions constant.
Jack for coaxial connection of a high frequency counter:
The adjusted frequency during the scan can be used to calculate the g value of a signal. The g value gives the absolute position of a signal.

Increase of microwave power range 100 W - 100 mW high power:
It is recommended for samples saturating at microwave power higher than 50 mW.
Increase of microwave power range 100 W - 50 mW low power:
It is recommended for samples at microwave power 100 W.
Holder and positioning system for a standard sample:
A simultaneous measurement of sample and standard is possible.
Inclusive is one secondary standard Chromium or Manganese of your choice (Order No A 30 10 014 or A 30 10 015).
Extended magnetic fi eld range 50-600 mT through water cooling:
The increase of the magnetic field range is recommended in the case you like to measure transition metal complexes of Fe (III) low spin.
The extension includes a compact refrigerated circulator with 240W cooling capacity.
