This section contains all the information needed for the laboratory work on the course. Start by selecting your lab group. You will do all lab work with the same group of people, including write the short lab report.
Lab points Folder
Here you can find the points earned from lab work. For the most part, you were evaluated as a part of your group. However, in some cases an individual evaluation was used: if you were late on many occasions, that decreased the amount of points for you, not your group. And if you were particularly active and helping people in your group, you might have gotten extra credit.
You can also find a file with some general comments on the reports.
Lab results from all groups Folder
Here you can find the numerical results from all groups, as calculated using my Excel-sheet. You can see that the mass of iron differs quite a lot depeding on the sample (because heavier pills have more iron in them), but the concentrations are around 210 mg/g in each determination. The errors for the titration and gravimetrical analyses were the smallest as one might expect for classical methods. For spectrophotometry and AAS, we had two instances where the results were quite clearly off (either because of a bad standard line or a single bad sample). If those are left out of the analysis, these methods also produce reasonable errors (although the large error in AAS speaks more for the condition of our tool than for the quality of the method in reality).
Also, you can compare our results with results obtained from 30 groups of Finnish students last year. It appears our iron concentrations are somewhat higher than they obtained.
Lab instructions Folder
Here you will find instructions for the different lab exercises we will do during the course.
Result sheets Folder
In this folder you will find the different result sheets that your group must fill out after each lab session. Return the sheets into the box for your group.
Lab report instructions File
Word 2007 document
This file constains instructions for writing the lab report. You can use this file as a templete when writing, since it has the correct formatting. Return the report into the box for your group.

Lab schedule (2nd version) File
This is the second version of the lab work schedule. For the lab work, we will be joined by Kuldeep, who is working on his PhD at our department. Kuldeep will instruct some of the exercises, while I take care of the rest. Your name tags will follow the color scheme used here to help you keep track of your groupmates during the first labs.
Choose your lab group here Group choice
Here you can choose your lab group. All lab work will be done in the same group! All lab groups work Tuesdays and Wednesdays 5.11. - 20.11. from 8:00 to 12:00, but will do the exercises in different order.
