CHEM 300 – Spring 2012 CHEM 300 – Spring 2012 Instrumental Chemistry and Analytical Methods Lectures: Monday, Wednesday, Friday 11 – 11:50 AM, Beaven 118 Instructor: Professor Amber Hupp Office: Haberlin 335 Telephone: 508-793-2502 Email: [email protected] Office Hours: Tuesday 1 – 3 PM, Wednesday 1 – 2 PM, Thursday 2 – 3 PM, Friday 2 – 3 PM, or by appointment Laboratory: Monday 1 – 5 PM OR Tuesday 8 AM – 12 PM, Haberlin 319 Lab Supervisor: Antonet DeSouza-Goding Office: Haberlin 312 Email: [email protected] Office Hours: Monday 9:30 – 10:30 AM, Thursday 1 – 2 PM Required Course Material: Principles of Instrumental Analysis, 6th Ed., by Skoog, Holler, & Crouch Chemistry 300 Laboratory Manual (available on Moodle) Bound laboratory notebook (carbon-less are okay) USB flash drive (for lab data) Scientific Calculator (graphing type are okay) Moodle is accessible from: http://www.holycross.edu/login/ Course goals: This course will focus on key concepts of quantitative and instrumental methods of analysis. Students will learn about molecular and atomic spectroscopy, electrochemistry, separation science, and mass spectrometry. Lecture and laboratory work will emphasize major analytical methods of analysis, instrumental design, and some method development. Students will learn how and why instruments are designed to operate according to specific criteria and should be able to make intelligent choices among several possible ways of solving an analytical problem. Prerequisites: Chemistry 231, Physics 111 or Physics 115 with laboratory (may be co-requisite) 1 Quizzes and Examinations: There will be two quizzes, three hourly examinations, and one final cumulative examination. See attached schedule for dates. Quizzes and exams will focus on lecture material, however, due to the integrated nature of the course, concepts and content from the laboratory portion will be included. Quizzes and exams are equally important, yet generally quizzes will cover a smaller amount of material and be held in a shorter amount of time than exams. Laboratory: There will be eight laboratory experiments designed to provide comprehensive details concerning instrumental methods of analysis. It is expected that you will come to lab prepared, having read the laboratory experiment, recorded pertinent experimental information, and completed any necessary calculations in your laboratory notebook ahead of time. Each week, a series of questions regarding the previous weeks lab will be given. The answers to these questions should be typed and are due as a group at the beginning of the lab. Three full laboratory reports will be written throughout the semester, two as a group and one individually. More details concerning these lab reports are located in the Chem 300 Laboratory Manual on Moodle and will be discussed in lab. See attached lab schedule for assignments and due dates. In the final weeks of the laboratory, an independent laboratory project will be completed. Your group of 2 students will be given a chemical problem and be in charge of determining the proper analytical technique (from data pretreatment to instrumental system to data analysis) to quantitatively analyze your sample. More details about the laboratory project will be given in class during the week of March 12. The laboratory notebook should be maintained over the course of the semester. To evaluate the notebook, two laboratory notebook quizzes will be given at the mid and end points of the semester during lab time. Guidelines for the lab notebook can be found in the Chem 300 Lab Manual. Attendance: While attendance at lecture is not required, it is expected. Partial lecture notes will be available on the Moodle course website. However, these notes will contain only an outline with significant graphs, figures, or diagrams, and do not substitute attending lecture. Attendance at all laboratories is required. An unexcused absence from lab will result in receiving a zero for that laboratory, as well as a 10% overall reduction in the laboratory grade. Please contact the instructor regarding any missed laboratories. 2 Missed Assignments: Make-ups for labs and exams will only be allowed with a Dean’s excuse, and must be arranged in advance if possible. If sickness arises, a Dean’s excuse will be required. In this case, please contact the instructor as soon as possible to arrange for a make-up. Late Policy: All laboratory assignments will be due at the beginning of lab. A penalty of 20% will be assigned for each day (24 hour periods, including weekends) that the assignment is late. After 4 days, no assignment will be accepted, and the student will receive a zero for that assignment. Re-grading: Please let the instructor know as soon as possible if you would like a re-grade or if your score is incorrect. No re-grades or grade corrections will be allowed more than one week after your assignment is returned to you. Academic Dishonesty: All work submitted for this class must be your own. Any student caught cheating or plagiarizing work will receive a zero for the assignment or for the course, depending on severity of academic dishonesty. In addition, all instances of academic dishonesty will be reported to your Class Dean and put in your file. Evaluation: Grades will be assigned based on the following scheme: Quizzes (2) 100 points ~ 12% Hourly Exams (3) 300 points ~ 38% Final Exam 150 points ~ 19% Laboratory 250 points ~ 31% Total 800 points 100% 3 Tentative Lecture Schedule Week Date Lecture Topic Other Jan 25 1 Ch 1 – Basics of Instrumental Analysis Jan 27 Statistics for Analytical Chemistry Jan 30 Propagation of Error, Significant Figures 2 Feb 1 Ch 5 - Noise Feb 3 Quiz 1 1, stats, 5 Feb 6 Ch 6 – Introduction to Spectroscopy 3 Feb 8 Ch 7 – Components of Optical Instruments Feb 10 Feb 13 Chs 13 & 14 – UV-Vis Spectroscopy 4 Feb 15 Catch-up and Review 1, stats, 5, 6, 7, Feb 17 Exam 1 13, 14 Feb 20 Ch 15 – Luminescence Spectroscopy 5 Feb 22 Ch 16/17 – Infrared Spectroscopy Feb 24 Ch 18 – Raman Spectroscopy Feb 27 Ch 8 – Introduction to Atomic Spectroscopy 6 Feb 29 Mar 2 Ch 9 – Atomic Absorption Spectroscopy Mar 5, 7, 9 No Class – Spring Break Mar 12 Ch 10 – Atomic Emission Spectroscopy Discuss Lab Projects 7 Mar 14 Catch-up and Review 15, 16, 17, 18, Mar 16 Exam 2 8, 9, 10 4 Week Date Lecture Topic Other Mar 19 Ch 22 – Introduction to Electrochemistry 8 Mar 21 Mar 23 Ch 23 – Potentiometry Mar 26 Ch 23 (con’t) 9 Mar 28 Ch 25 – Voltammetry Mar 30 Quiz 2 22, 23, 25 Apr 2 Ch 26 – Introduction to Separation Science 10 Apr 4 Apr 6 No Class – Easter Break Apr 9 No Class – Easter Break Prelab proposal Apr 11 Ch 26 (con’t) 11 approval due Apr 13 Ch 27 – Gas Chromatography Apr 16 Ch 27 (con’t) 12 Apr 18 Ch 28 – Liquid Chromatography Apr 20 Apr 23 Ch 30 – Capillary Electrophoresis 13 Apr 25 Catch-up and Review Apr 27 EXAM 3 – Separation Science 26, 27, 28, 30 Apr 30 14 May 2 Chs 11 & 20 – Mass Spectrometry May 4 15 May 7 Final Review 5 Laboratory Schedule What’s Due?

A chemical revolution (or rupture, discontinuity, transition) mainly by emplacement, instead of replacement, procedures were identifed by: a radical reinter- pretation of existing thought recognized by contemporaries themselves, which means the appearance of new concepts and the arrival of new theories; the use of new instruments changed the way in which its practitioners looked and worked in the world and through exemplars, new entities were discovered or incorporated; the opening of new subdisci- plines, which produced, separated scientifc communities.

  • Mass Spectrometry-Based Investigations to Characterize Specific Cell Types Within the Brain
    MASS SPECTROMETRY-BASED INVESTIGATIONS TO CHARACTERIZE SPECIFIC CELL TYPES WITHIN THE BRAIN BY ANN M. KNOLHOFF DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Chemistry in the Graduate College of the University of Illinois at Urbana-Champaign, 2011 Urbana, Illinois Doctoral Committee: Professor Jonathan V. Sweedler, Chair Assistant Professor Ryan C. Bailey Professor Martha U. Gillette Professor Alexander Scheeline ABSTRACT Investigations of the chemical content of the brain and its many constitutive cell types yield information regarding normal and abnormal brain function. Frequently, proteomics, peptidomics, and metabolomics experiments survey brain regions and attribute detected species to neurons. However, many other cell types are present, including astrocytes, oligodendrocytes, and microglia. It is also known that different cell types can vary greatly in their analyte content and concentration; therefore, to obtain an adequate representation of brain function, specific cell types require further characterization. Cell types of particular interest are astrocytes, which are involved in neuronal communication, and mast cells, which are involved in allergic response. Moreover, morphologically similar cells can exhibit chemical heterogeneity; to characterize these differences, single-cell analyses are necessary. In this case, single cells from the model organism, Aplysia californica, are isolated for analysis. Mass spectrometry (MS) is well-suited for such applications because it has limits of detection in the attomole range for both small molecule metabolites and peptides, has a wide dynamic concentration range, and can detect and identify molecules of interest without a priori knowledge of sample content. To characterize metabolite profiles in single cells and tissue homogenates, a laboratory-built capillary electrophoresis (CE) system coupled to electrospray ionization (ESI) MS is implemented.
