CAFFEINE PROJECT: How Much Caffeine is in This Drink? (Modules 3 and 4)
Caffeine I: Create and Validate Calibration Standards Using Serial Dilution and UV-Vis Spectrophotometer (Module 3)
Usually, Module 3 is completed on the first (week I) of the three-week sequence for this project. Your goal for this week is to create the caffeine CALIBRATION STANDARDS using serial dilution.You will check whether you have done this well using UV-vis. Just as you did in module 2, you will use UV-vis absorbance to create a calibration curve ov absorbance vs concentration. Then, you should us a VALIDATION STANDARD (ie a "control" solution) to validate the calibration curve. SAVE SOLUTIONS so you can use them next week! You can move onto Module 4 only after you can validate your calibration curve. If not, you must repeat Module 3 during the second week of this project (hopefully better and more quickly on the second try).

Caffeine II: Determine Caffeine in Beverages Using HPLC
Usually, Module 4 is completed on the second week (week II) of the three-week sequence for this project. If you successfully validated your calibration curve in week I, you can immediately begin working on the HPLC under the supervision of a TA. Students who must repeat Module 3 should consult with the TA about how to proceed (usually it involves repeating Module 3 first then immediately moving on to Module 4 and letting the instrument robot work for you overnight).

Caffeine III: Finish Lab Work and Data Analysis and Writing
Week III of this project can be used to repeat lab work as necessary. When lab work is finished, this time should be used to make as much progress on your report as you can with TAs on hand to answer questions. Refer to "final" plot expectations from your prerequisite P-Chem lab course, and do include estimated error for all measurements and calculated concentrations.
COCAINE PROJECT: How Much Cocaine is in Your Pocket? (Module 5)
Cocaine I: Practice Manual Injection and Create a Preliminary Calibration Curve Using GCMS
The GCMS requires time-intensive manual injections. Your goal for this week is to run all of your standards and your sample and to process your data so you are sure that the calibration curve is in the appropriate range for your sample. While you are doing this, you are also learning how to use the GCMS and how to do manual injections well. If you are careful and read all directions carefully, this usually goes well. But there are lots of pitfalls - be sure to carefully and slowly read directions, and follow the time saving tips in the manual. Use the 10-minute waiting periods between injections to complete data analysis and writing. Use a timer! SAVE YOUR SAMPLE SOLUTION so you can use it next week! Expect to continue data collection over the entire scheduled time for Week I and II meetings.

Cocaine II: Create a Final Calibration Curve (run in triplicate) and Determine Sample Concentration
Plan to repeat the work from last week to accomplish an additional two injections of each calibration point and of the sample. Use the 10-minute waiting periods between injections to complete data analysis and writing. Use a timer!

Cocaine III: Finish Lab Work, Data Analysis, and Writing
If things go smoothly on the first two days, this period can be used for writing. However, if you do run into issues or have not been able to collect usable data, then it is expected that the time in Week 3 is used for data collection. Please note that the GCMS instruments often have issues and this week is often used for data collection.
WATER ANALYSIS PROJECT: How Well Do Water Filters Work? (Module 6)
Water I: Create calibration solutions
Please arrive at the begriming of lab with your water in hand. The first thing you should do is to discuss you calibration strategy with your TA. You should also discuss how you will validate your calibration curve, if you plan to do so. Once you are certain of your plan, you may proceed to preparing your calibration solutions (be sure to rinse all glassware in dilute nitric acid to remove trace metals). The goal is to end the period with data indicating a linear response to your sample concentration. If necessary, continue data collection overnight using the instrument autosampler.

Week of LDOC: No Lab Meeting
No lab meeting this week (because of short week). Any late assignments must be submitted prior to end of day on LDOC. No work will be accepted for scoring after this time.
