Advanced
topics in chemical instrumentation including programming in LabView,
Analog to Digital converters, Digital I/O, Timers, Computer Interfacing
using RS-232 and GPIB communication protocols, Noise Reduction
strategies, and Fourier Techniques such as Apodization. At the
end of the class there are two special projects to apply this
knowledge: (1) a Flash Photolysis experiment (lifetime measurement
of an excited state), and (2) construction of a computer-controlled
automatic titrator.

| Textbook |
No text - I
will assign reading from a variety of sources including the text
used in Ch 313, "Principles of Instrumental Analysis",
Skoog, Holler, & Nieman, 5th ed, and "Laboratory Automation
Using the IBM PC", Gates & Becker (out of print so I will
furnish handouts). |
| Lab |
I will furnish
handouts. We will be using a program called LabView 7 Express for
all of our computer interfacing and data acquisition. |
| Exam
Policies |
There are
no make-up exams except for University sanctioned events, in which
case please see me a week in advance for an alternative testing
time. In the event of an unexpected emergency, then -
Midterms: Family-related emergencies or deaths must be
communicated through the Office of Student Affairs (838-8221)
and broadcast to all your professors. Illnesses must be accompanied
by a note from your doctor. Under these conditions there are two
options for replacing the midterm score:
(1) If the exam hasn't been handed back to the class yet, then
arrange a make-up time with me.
(2) If the exam has already been returned to the class, then I
will replace the missing hour exam score by taking 30% of the
percentage you receive on the final exam (since it is a 150 pt
exam) and 70% of the other midterm score. This option can obviously
only be used once.
Final exam: University policy states that the final exam
time will not be moved. Please do not ask to take the final early
because you want to leave for vacation early! There are exceptions
such as starting a new job, etc. See me if there's a problem.
Again, if you miss the final and follow the same procedure listed
above under midterms, then I will give you an incomplete and you
can take the final in a future class section to make it up (see
Incompletes section below).
|
| Incompletes |
Incompletes
are given under special circumstances such as medical reasons, family
emergencies, etc. In order to receive an incomplete, the University
requires you to sign a contract with me outlining the steps you
must take to finish the course. Usually this means there will be
a time deadline for completion of the course before your grade reverts
to an "F". |

| Academic
Dishonesty |
The Code
of Student Responsibility defines cheating as "intentional
use, or attempted use of artifice, deception, fraud, and/or misrepresentation
of one's academic work". For this class, which involves taking
exams, quizzes, and perform labs, cheating is usually but not
limited to talking or writing to other students, using crib sheets
(prepared notes), or looking at another student's paper. The penalty
for cheating will be a zero grade for the test or quiz or assignment
in question.
Students have
the right to appeal this action as described in the Code
of Student Responsibility
