CHE -302 Lab 1 Chemistry 302: INSTRUMENTAL ANALYSIS Cedar Crest College Dr. Brettell, Spring 2009 Office: Oberkotter Rm #6 Lab Sections 01, 02, 71 Office Hours: Tues., Thurs., and Fri. 10:00 AM – 12:00 NOON (or by appointment) Email: [email protected] Phone: 610-606-4666 Ext. 3495 INSTRUMENTAL ANALYSIS LABORATORY In the Instrumental Analysis laboratory, students will be working individually in groups of three (3) or four (4) to complete the twelve (12) experiments. Each individual experiment will be described in the laboratory manual or handout provided by the instructor. Each student should read and understand the material described in the laboratory manual and handouts before performing the experiments. The laboratory manual will also contain a detailed list of the requirements for the laboratory reports. WORKING IN GROUPS: Each group of students will cooperate to perform an experiment together. One laboratory report is to be submitted by each group of students for each of the twelve (12) experiments. Before beginning an experiment, the group should select a group leader. Each member of the group should serve as leader for at least three (3) of the twelve (12) group experiments. The responsibilities of the group leader are as follows:  Coordinate the work required to complete the experiment and prepare the report. Try to delegate tasks as equally as possible among the group members.  Make sure that all of the group members have a complete set of the data obtained in the laboratory.  Assemble the parts of the report.  Make sure that the other group members have an opportunity to review and revise the entire report before it is submitted.  Ensure that the report is submitted to the instructor by the due date. Reports are due the next laboratory class after the completion of the experiment, with the exception of the final experiment, which is due 48 hours after checkout day (the last lab period of the semester). Note that it is NOT the responsibility of the group leader to write the entire report. The writing of the report should be a group effort. In general, all members of a group will receive the same grade for an experiment. Therefore EACH group member is responsible for insuring that her work is reflected in the report. In the event that there is disagreement among the group members concerning the content of any part of the report, any member is free to submit her own version of the topic in question.CHE -302 Lab 2 LAB SCHEDULE Attendance in the laboratory is MANDATORY. All twelve (12) experiments must be completed as scheduled and reports submitted when due. The laboratory will operate on a semi-open lab policy. That is, lab work is possible at times other than and including the officially scheduled lab period. As you all have had two plus years of training in Chemistry, it is expected that you can work safely with a minimum of supervision. An instructor must be present at all times. There will be twelve (12) laboratory experiments. Students will work in groups of three (3) or four (4) on all experiments. For each experiment, each group will submit one laboratory report along with answers to the post-lab questions two weeks after completing the lab. Each individual student will submit her own laboratory notes with the report. Laboratories will be performed on a rotating schedule with the class divided into three groups. During any laboratory period, each group of students will be working on a different experiment. Hence, the specific dates on which a given experiment will be performed will differ for each group of students. A detailed schedule is provided below: Week # Date Exp# Title of Lab Experiment Student Schedule 1 20-Jan Check In; Laboratory Orientation; Review of Laboratory Safety Policies and Procedures Grp I Grp II Grp III Week of 1/27 Week of 2/3 Week of 2/10 2 27-Jan 1 Determination of Balance Error Grp I Grp III Grp II 3 3-Feb 2 UV-Visible Spectrophotometry, pKa of an Indicator Grp II Grp I Grp III 4 10-Feb 3 1-H NMR Determination of a Drug Mixture Grp III Grp II Grp I Week of 2/24 Week of 3/3 Week of 3/17 5 17-Feb No Scheduled Lab- Catch-up 6 24-Feb 4 Fluorometry, Analysis of Quinine in Tonic Water Grp I Grp III Grp II 7 3-Mar 5 Infrared Spectrophotometry Grp II Grp I Grp III 10-Mar Spring Break 8 17-Mar 6 Basic Gas Chromatography/Mass Spectrometry; Analysis of an Unknown Drug of Abuse Grp III Grp II Grp I Week of 3/24 Week of 3/31 Week of 4/7 9 24-Mar 7 Atomic Absorption: Analysis of Gunshot Residue Grp I Grp III Grp II 10 31-Mar 8 GC, Qualitative & Quantitative Analysis of Alcohols Grp II Grp I Grp III 11 7-Apr 9 GC/MS of Fire Debris Accelerants Grp III Grp II Grp I Week of 4/14 Week of 4/21 Week of 4/28 12 14-Apr 10 HPLC: Qualitative Analysis of Goldenseal Alkaloids .Grp I Grp III Grp II 13 21-Apr 11 Pyrolysis GC/MS of Paints Grp II Grp I Grp III 14 28-Apr 12 LC/MS/MS of a Drug Mixture Grp III Grp II Grp I 5-May Friday Lab Section OnlyCHE -302 Lab 3 It is unavoidable that the lecture and laboratory will not move at the same pace, nor cover subjects in the same order. It is therefore, imperative that you learn as much as you can about each experiment by reading BEFORE you come to the lab. Be sure to read the appropriate chapters in the lecture text and the lab description before performing an experiment. LABORATORY NOTEBOOKS Suggested laboratory notebook: Laboratory Notebook, W.H. Freeman and Company. A copy of your laboratory notes from your notebook must be attached to your laboratory report. LABORATORY REPORTS The laboratory reports required for this course in Instrumental Analysis should be detailed accounts of your work in the laboratory, including an organized collection of your measurements, summary of your computed results, and answers to a set of questions to be completed at the end of each experiment. Laboratory reports should be concise, well organized, and in correct English. They should be on 8-1/2 x 11 inch paper with reasonable margins. Typewritten reports are preferable. It is strongly recommended that you use a word processing program such as Wordperfect® or Word®. However, NEAT, legible handwritten reports (in blue or black ink only) are acceptable. The pages of the report should be bound together in some manner, such as
