New Life of an Old Spectrometer:An Innovative Experiment Based on the Digitization of an Obsolete Instrument
摘要
Abstract
Today,commercial analytical instruments used in teaching are often enclosed and highly automated,which,while convenient for routine analysis,can hinder the demonstration of instrument components and operations during the teaching process.To address this issue,we modified an old nuclear magnetic resonance(NMR)spectrometer to enable digital signal output.By replacing its mechanical recorder and cathode-ray tube oscilloscope with a data acquisition card and custom software,we successfully facilitated the display,manipulation,and storage of spectra on a computer.This modification enhances the instrument's suitability for teaching,allowing for more direct observation and hands-on operation,thereby improving students'understanding and stimulating their innovative thinking.It significantly enhances the educational outcomes of instrumental analysis experiments.关键词
