The 378 lab is designed to teach how individual skills, once mastered, can be combined into progressively larger group efforts, working with progressively larger instrumental systems, eventually culminating in a public presentation and discussion of a fully computer-based, custom liquid chromatography instrument. The way that the experiments are organized is first shown in the block diagram below, and then in the individual laboratory experiments that are tagged as links to typical results from past lab students. The actual calendar for the Fall, 2001 offering can be viewed for specific dates on which the experiments will be performed.
I have been fortunate to have support from The Dow Chemical Co. Foundation and the Zymark Co., collectively, to use a Zymark Zymate II Laboratoy robot in my teaching of instrumetal analysis. I used it between 1991 and 2003, in the manner shown here and for the experiments shown below. I am indebted to these companies and to Dr. Mel Koch and Mr. Frank Zenie for their endorsements and encoiragement in this exciting stages of my career.

The Fall, 2002 offering is a special one. It is the last time teach this (or any) analytical chemistry course. After that, I retire and move on to other challenges. For most of my adult career I have wanted to teach an instrumental course that emphasized primarily pure instrumentation and modern interfacing electronics. This last offering has been that. The calendar for Fall 2002 shows how this was done. It may not meet the ACS CPT requirements, but it is what I truly believe should be offered in this last analytical course that most undergraduates will take. It took me from 1964 until fall, 2002 (and two academic institutions) to teach this one course the way I believe it should be taught, but it was worth the wait and all of the political struggles. Most of the experiments use LabVIEW® as the primary software environment for data acquisition, processing, display, and storage. The LabVIEW® "virtual instruments" (VI's) we use for the experiments are available for downloading as "stuffed .sit" binary Mac files by clicking here. If you wish to download a "portable data format" (x.pdf) version of a complete experiment writeup, without the LabVIEW® VI's, then click here.
The way in which the experiments expand from individual execution to whole group collaboration is shown in the diagram below.
