    Abstract

    A basic 60-MHz nuclear magnetic resonance (NMR) spectrometer (Varian EM360A) can be economically upgraded by external connection to an integrating chart recorder (Shimadzu C-R3A). The analog voltage signal corresponding to vertical pen position for signal peaks on the spectrometer's flatbed recorder can provide an input signal to the external recorder. Major benefits include improved objectivity in quantitation by digital electronic integration of peak areas, ability to reprocess spectra stored in memory, and improved tracing of fast signal peaks. Details of the interfacing procedure and a discussion of results are provided.
