摘要：
We have described a laboratory activity for an upper-level undergraduate course in instrumental analysis that teaches the fundamentals of LabVIEW and interfacing through construction of a fluorimeter from modular components. Students use a DAQ module and LabVIEW to interface a desktop computer with a blue LED light source and photodiode detector. In addition to measuring a calibration curve for fluorescein, students have investigated the Stern-Volmer quenching of fluorescein by iodide and the pH dependence of fluorescein fluorescence.
