MIXED ACIDS ANALYSIS BY NMR.
Abstract
This report relates the progress that made toward completion of proton/nitrogen-14 signal intensity ratio measurements on static samples of mixed nitrating acids. Because existing instrumentation did not give the accuracy required of these measurements, this work proceeded through a series of instrument modifications designed to increase signal/noise ratio, to improve stability, and to provide for greater speed and convenience of operation. The magnetic field is now modulated with a triangular wave at a frequency of 10/ sec, and the growth of the integral of the resulting 20 signals per sec is measured over a one-min. period. The circuitry implementing the technique is shown, the technique discussed, and results obtained are presented. (Author)
