Analytical and Instrumental Chemistry 

Leslie Hiatt in Lab

Dr. Hiatt enjoys teaching students how to quantitate analytes and how to use instruments to analyze complex samples. She mainly teaches general chemistry, quantitative analysis, and instrumental analysis. General Chemistry is the first course a chemistry major takes and teaches students the basics needed in all levels chemistry. Quantitative Analysis teaches students how to develop good experimental protocols and then how to properly analyze data using numerical evidence. Instrumental Analysis builds on the skills developed in Quant to teach students how to use instruments to perform more advanced analysis of samples. The students in this course become experienced users of all the advanced instruments our department has to offer.

Advising: Dr. Hiatt advises chemistry majors and pre-pharmacy majors.

She loves working with students in the classroom and in the lab. Read below to find out about her research and to find out how you can become involved in undergraduate research!

Dr. Hiatt's Schedule and Chemistry Department Events and Seminars

There is nothing more inspiring than a well done seminar. We hope some of the speakers this semester will inspire you. Please see the calendar below for scheduled office hours, seminars, activities, and outreach.

 

Electronic cigarettes are gaining popularity across the globe. Marketed as a helpful tool to aid smokers who wish to quit, electronic cigarettes deliver nicotine to users as a vapor without additional chemicals found in tobacco products. Currently, electronic cigarettes are not under the authority of the Food and Drug Administration, since they do not contain tobacco. Without regulation, not only is the effect of these cigarettes not known, the content of these products has not come under close analytical scrutiny. Our lab, in conjunction with Dr. Meagan Mann, are attempting to determine the nicotine content in electronic cigarettes. Can consumers trust the labels that describe the amount of nicotine in each liquid refill bottle? Does the content vary across batches? Does it change significantly over time and after the liquid’s expiration date? Our research utilizes electrochemistry and other instrumentation to answer these questions.

 

Carotenoids are organic pigments that occur naturally in plants and other photosynthetic organisms. When you see the beautiful oranges, reds, and yellows of fall foliage; you are seeing a few of the vibrant colors associated with carotenoids. Carotenoids have reversible electrochemistry and have shown an electrochromic response to changes in membrane potentials. The changes in absorbance already identified allow us to hypothesize that the characterization of carotenoids would lead to the identification of an electrochromic material suitable for incorporation into an electrochromic device such as an electronic reader.

If you are a student who enjoys asking questions, inventing new ways to approach problems, and you would like to work on an exciting problem that involves chemistry, biology, electricity, and technology, drop by my office to discuss possible research options. This research is in the field of bioanalytical electrochemistry and has many facets.
