摘要
A probe for detecting and dosing molecular oxygen by the electronic paramagnetic resonance spectrometry of a sample of lithium phthalocyanine in contact with the atmosphere to be tested. The probe includes a fixed glass tube with the shape of a hairpin, traversed by a flow of an atmosphere to be tested. The top of the tube contains a chamber with porous walls traversed by the flow of the atmosphere to be tested. The chamber contains the phthalocyanine sample and is surrounded by the spires of an electronic resonance detector trip coil. A movable magnet surrounds the tube and is provided with windings to create a continuous field for polarizing the phthalocyanine sample.
