probe for detection and dosage of molecular oxygen by has paramagnetic elektronenresonanz spectrometry

摘要

Probe for the detection and determination of molecular oxygen by electron paramagnetic resonance spectrometry of a sample of lithium phthalocyanine in contact with the atmosphere to be monitored, including: - a hairpin-shaped stationary glass tube 2 carrying a flow of the atmosphere to be monitored, at the top 8 of which a chamber with porous walls 10, through which the above flow passes, contains the sample of phthalocyanine and is surrounded by the turns 30,32 of the exciting coil for detection of the electron resonance; - a removable magnet 34 capable of fitting around the tube 2, this removable magnet 34 being provided with windings 38 which make it possible to create the continuous field IMAGE for polarising the sample of lithium phthalocyanine and the oscillating field for scanning this polarisation IMAGE .
