• Resumen

  • Our application of LabVIEW(R) software for computer data-acquisition using several techniques used across our curriculum is described. The techniques are gas chromatography, calorimetry, titrations and other volume-dependent techniques, spectrometry for kinetics using a Spectronic 20(R), and emission spectroscopy. Applications of these techniques range from general chemistry to physical chemistry, instrumental analysis, and undergraduate research. The hardware in common for all of the techniquesis a 4-1/2 digit multimeter connected to the computer via a GPIB interface to a Macintosh computer. Figures include examples of a LabVIEW "virtual instrument" (VI) diagram, some student-generated data, and a LabVIEW VI front panel.
