A Proposal to Combine of CHEN 5503 Instrumental Analysis of Process Products With CHEN 49093 Unit Operations Laboratory Preface: ChEN 5503 is to see 36 students in two sections for the first time next Fall. This fall one section had 14 students and the other had 6 students. Problems with the 14 student section had most to do with equipment availability due the structure of the courses. CHEN 5503 Instrumental Analysis Class Structure is to have all students working on one or two pieces of equipment. Schedule is given below. Grading: Scaled curve with the highest score received corresponding to 100% Notebooks – 10% Midterms – 30% Memo Reports – 60% Lab SOP’s Material Due Physical Properties Lab MEB 3215 Orientation Measuring Wt% Lectures Course Overview, Moisture Laboratory Safety, TH Aug Guidelines for Ch. 1 Density by Density Making Physical Questionnaire 25 Preparation of Lab Ch. 4 Meter Measurements, Reports Reading a Error Analysis I Hydrometer (TR) Refractive Index of a Liquid Sampling, Sample Prep., Notebooks, Sampling, Physical Properties pp. 2-17, Bring dry dog or T Aug 30 Property Characterization Measurement Techniques Lab 38-43 cat food sample (KR) (practice) Literature Review Physical Thermal Analysis Ch. 6.1, Th Sep 1 Thermal Analysis Properties/Thermal Physical Properties 6.2 (TR) Analysis Lab Laboratory Report Thermal Analysis Physical Preparation (TR), Ch. 7.1, Physical Properties T Sep 6 Properties/Thermal Notebooks Atomic Spectroscopy 11.6 Lab Analysis (KR) Bring Gatoraid like Sieve Analysis Physical Properties / TH Sep 8 Midterm I Analysis for Metals juice drink of you Atomic Absorption choosing Intro to Molecular Physical Properties / Ch. 8.1, Metals in a Juice Physical Properties T Sep 13 Spectrometry (TR) Atomic Absorption 8.2 Drink Memo Report Prepare Standards UV/Vis Spectrometry UV/Vis Introduction & Ch. 8.3, TGA TH Sep 15 UV/Vis Spectra & and Colorimetry (KR) Prepare Standards 8.4 Memo Report Analysis Lab Infra red Spectrometry IR/FTIR Spectra & T Sep 20 IR/FTIR Analysis Ch. 8.5 Notebooks (TR) Analysis Lab Separations and Ch. 9.1, Analysis for Metals TH Sep 22 IR Analysis Problem Chromatography (KR) 9.2 Memo Report LC/GC Instruments and Introduction to Gas & Gas & Liquid T Sep 27 Ch. 9.2 Methods (KR) Liquid Chromatography Chromatography Date Lecture Topic Lab Topic Reading TH Sep 29 Quantitative GC, Troubleshotting (KR) T Oct 4 Midterm II Process Analytical Chemistry (TR) Process (on-Line) T Oct 11 Analysis – Components (TAR) Process (on-Line) TH Oct 13 Analysis – Systems (TR) Gas/Liquid Analysis Problem Gas/Liquid Analysis Problem TH Oct 6 Ch. 9.2 HPLC Procedure for Testing Sugars UV-Vis/FTIR Memo Reports Last Labs GC/LC Memo Reports Open Lab Project Open Lab Project Notebooks Open Lab Project/ Lab Cleanup Last Lab Memo Report T Oct 18 (15 meetings over 8 wks) Memo Reports (8) are 2 to 3 pages long and a good place to get CLEAR involved with the students’ writing. Problems with this structure to the class: 1.) Accommodating large student numbers. 2.) Lab Techs being responsible for a new piece of equipment every week. Before they have gotten the hang of the software on one piece of equipment they need to be proficient on another piece of software. 3.) Equipment is not used efficiently. 4.) Reports are coming in at a pace of one per week but only after the 4th week of class. Work overload by Students after week 4.. Grading overload by Professor after week 4. 5.) An experiment can not be started until the lecture material has been given on that instrument and methods. 6.) Students can follow SOP’s but can not develop analytical methods.

Lecture Time for CLEAR Teams Writing Reviews Oral Presentations Other Fixed Laboratories for 8 weeks. Do 4 Labs. The laboratories are rotated between the groups. No lecture materials are given. The students are required to research the equipment and methods and prepare a plan to the instructor (Oral Quiz) before they are allowed to operate the equipment and do their experiments. Fixed Laboratory Assignments 1) Develop analytical methods for a. The Atomic Absorbance (AA) spectrometer, and b.
