1 LabVIEW® Tutorials A set of VI's are illustrated to be used during the first lab session to guide reading in the Student Edition book before the first experiment on Digital Input/Output.
 1.2 MB 
LabVIEW® Tutorials.pdf
2 Operational Amplifiers A set of 3 wiring projects involving a voltage follower to make an active attenuator, a current follower to read the output of an LED, and an instrumentation amplifier to read a thermocouple output. (Many close-up photos used increase this one's file size.) 32.6 MB OA.pdf
3 Digital Input/Output BCD encoding, switching with solid-state relays, and parallel interfacing of a commercial pH meter are done. The response time of a commercial glass pH electrode is measured on a VI display. 1.7 MB  DIO.pdf
4 Serial Input/Output Years of work have gone into this experiment. It is now more relevant than ever given the number of instruments with serial interfaces. The full RS-232 protocol is studied, using oscilloscopic monitoring of transmitted ASCII characters, interfacing a serial A/D converter, and LabVIEW ® operation of an inexpensive Metex® digital voltmeter. The large file size is due to the many high-quality photographs included in the write-up. 55.2 MB SIO.pdf
5 Analog/Digital Conversion The basics of A/D conversion are learned using LabVIEW® virtual instruments on three types of signal sources, e.g., a phase-shifted function generator, a pH electrode, and a low-level thermocouple. 2.0 MB A2D.pdf
6 Digital/Analog Conversion A set of time-varying waveforms related to common chemical signal sources and processes are generated from formulas and outputted via a LabVIEW® D/A converter VI to a strip chart recorder. 2.0 MB D2A.pdf
7 Mock GC Oven Controller The principles and techniques of Experiments 1-5 are combined into one instrument that mimics a temperature controller for a GC oven. Students build the temperature-controlling LabVIEW® VI. 1.0 MB Oven.pdf
8 Staircase Polarography Using a set of operational amplifiers for a potentiostat, a LabVIEW® VI applies a potential to a homemade, time-synchronized, dropping mercury electrode to record a classical staircase polarogram. 1.0 MB Polaro.pdf
9 Cyclic Voltammetry The same potentiostat as above is modified in LabVIEW® to allow recording a cyclic voltammogram from a solid, gold electrode. 500 KB CV.pdf
10 Atomic Absorption Standard addition methods are done by a Zymark® laboratory robot and a LabVIEW operated A/D system to read out an atomic absorption spectrometer to determine Fe and Cu in St. Olaf water. 724 KB AA.pdf
11 FT/IR Product Evaluation FT/IR is used with commercial, Excel® and LabVIEW® software analysis to determine if commercial, clear, spray paints, lacquers, and urethanes are compositionally unique, or just marketed that way. 3.5 MB FTIR.pdf
12 Robot Tutorials Guided tutorials on how to program a Zymark® laboratory robot for aspirin sample preparation and spectrometric analysis are given. 580 KB Robot Tutorials.pdf
13 Aspirin Hydrolysis The Zymark® robot is used to prepare an aspirin sample for periodic spectrophotometric analysis over the next 7 days to determine its pseudo first-order hydrolysis rate constant in buffered solution. 4.2 MB Aspirin.pdf
14 HPLC Automation Semi-automated HPLC instruments and LabVIEW® data stations are used as teaching tools to explain to the public how HPLC could be used to monitor a suspected gasoline spill. 2.2 MB HPLC.pdf
