The GC-MS is a very sophisticated instrument, here being used by a student for his senior research project. The GC is less sophisticated, but still gives good results. Here it is being used by a student in Quantitative Analysis. Potentiometric titration with a Vernier Software lab interface, operated by Jeremiah Myers Shown here are more students in Quantitative Analysis. The AA is a sensitive instrument for doing chemical analyses.
Potentiometric titrations are more routine, but can be computerized.
