Abstract
The Bruker TE(104) double rectangular cavity is commonly utilized for quantitative electron paramagnetic resonance (EPR) spectrometric measu rements. The sample, together with an appropriate standard, can be stu died simultaneously within such a cavity under identical states of mac hine tuning and parameter settings. However, even under such condition s, there still remain sources of error arising from sample size, shape and positioning of the sample tube within the cavity, In this paper s uch sources of error have been investigated and a procedure to minimiz e the errors by precision insertion of the sample tubes within the TE( 104) cavity is described.
