Introduction:
Chemical analysis methods
are used in many areas, such as biotechnology, pharmaceutical, environmental,
geological, materials development, forensic, medical, nutritional, energy and
industrial labs every day and have a profound impact on decisions made around
the globe. Scientists and engineers conducting
research and development for these industries often seek answers to chemical
identity, structure, or amounts questions. As such, chemical analysis plays a
critical role in scientific discovery and the quality of our
lives. Qualitative and quantitative methods of
chemical analysis for organic, biochemical, and inorganic compounds fall into
two categories, classical (or wet) methods and instrumental
methods. Although there is not always a
clear barrier between the two, the primary difference arises from the type of
physical property used to provide information. Classical methods often rely on
reactivity or physical properties such as solubility, color, melting and/or
boiling points, odors, optical activity or refractive indices for qualitative information, while
gravimetric, volumetric, and titrimetric measurements provide quantitative
information. Classical methods for the
separation of mixtures are mainly solvent extractions, precipitation, and
distillation. Instrumental methods of analysis typically utilize other physical
properties such as absorption or emission of light, mass-to-charge ratio,
electrode potential, current, or charge measured with modern sophisticated
electronic devices. Separations are
carried out by more efficient chromatography and electrophoresis methods.
Unfortunately, some scientists view and utilize these instruments as
"black boxes". The term implies a device in which the scientist
places a sample and somehow a number is generated that influences the
scientist's decision-making process. It should be apparent that this approach
could be dangerous, as the old saying "Garbage In/Garbage Out" is
often true. As such, any scientist using sophisticated instrumental equipment
needs at least a basic understanding of how these devices are designed to work.
Winthrop University's faculty adopted a set of four "University Level Competencies (ULCs)" that describe the qualities our students develop during their Winthrop career. It is easy to see that this course involves solving problems and developing written communication skills. However, you will also learn the responsibilities of chemists to the greater good of our planet and society, as well as the global nature of the chemistry enterprise. Within the discussions of chemical analysis instrument design and applications to the environment, health and materials we use every day, I think you will find this course fits well with all four competencies.
You will be using sophisticated mathematical and descriptive methods to solve problems found in environmental, pharmaceutical, biomedical, energy, food, forensic and electronic fields, for example.
Chemistry touches 95% of everything we use, daily. Chemists must be critically aware of industry impacts on the environment and human health.
Chemistry is a global enterprise with many industries located around the world that impact our quality of life. Chemistry is a core topic, touching most fields of interest from science, to art, to technology.
Science, in general, is difficult to understand, so correct, clear and effective communication methods are key. Peer review is fundamental to scientific communications.
Course Goals:
Instrumental Analysis is a broad and
continually expanding subject as new technologies emerge, but these methods can
generally be categorized as spectroscopic, electrochemical, or
chromatographic. In this course, we will
essentially take the cover off these "black boxes" to see how these
instruments are constructed and how measurements are made from the underlying
chemical and physical properties of the substance. In fact, you are likely to see
instrumentation represented from other courses you've taken, demonstrating the
broad impact instrumentation has in science. Quantitative problem solving will be utilized as a means to demonstrate
the chemical and physical principles applied to the design and performance of
instruments.
The
goal of this course is NOT to make you an "expert" on every type of
instrumentation to be encountered in a science lab, but rather to introduce and
educate you to the common principles as well as the variety of instrumentation
available for chemical analysis and the type(s) of information these
instruments provide. It is my hope that you will then expand your knowledge of
the instruments you come into contact with during your scientific career,
thereby avoiding the "black box" problem.

Attendance:
You are expected to attend each class meeting
for the full scheduled time. Instrumental Analysis is a difficult upper-level course and this
will help you to concentrate on the appropriate material and reinforce the
assigned readings and problems. You are
required to bring pencil, paper, textbook, and a scientific calculator to each class. Cell phone calculators are not acceptable.
Accessibilty:
Winthrop
University is dedicated to providing access to education. If you require specific accommodations to complete this course, contact
the Office of Accessibility at 323-3290 (Macfeat House),
http://www.winthrop.edu/student-affairs/accessibility.. Once you have your
official notice of accommodations, please let me know as early as possible in
the semester so we can plan.
AI Statement: Understanding how and when to use generative AI tools (such as ChatGPT, DALL-E) is quickly emerging as an important skill for future scientists. To that end, you are welcome to use generative AI tools in this class as long as it aligns with the learning outcomes and goals associated with an assignment. You are fully responsible for the information you submit based on a generative AI query (such that it does not violate academic honesty standards, intellectual property laws or standards of non-public research you are conducting through coursework). Your use of generative AI tools must be properly documented and cited for any work submitted in this course.
