Lab Report & Notebooks

    • The Lab Schedule for 2013 is found at the following LINK

    • Formal lab reports are required.  This means that they must be type-written and follow the specified format.  Each person in the group must turn in a lab report.  This does not mean multiple copies of the same report.  Write the report in your own words.

      Prepare a title page with the following information:

      Course Title (Instrumental Analysis and Separations, FOS 6355)

      Title of the experiment.
      Date the report was prepared.
      Your Name 
      Name of lab partner or partners.

      Prepare the report with the following sections:

      Most of the time you will be given some reference material with the lab handout.  Read this information and include in your report some of the topics that you found most interesting.

    • Objectives of the Exercise.
      Two or three sentences is generally enough unless there are multiple experiments.

    • Materials and Methods.
      Be brief, there is no need to just rewrite your handout.  However,  make sure to discuss any changes that were made to the procedures.

    • Results and Discussion.
      Include sample chromatograms.  You do not need to insert all of your chromatograms, just the most important ones.  Include data in table format if appropriate and include all calibration curves in graphical format.  Include sample calculations.

    • Answers to Questions (if any).
      If there are no questions, you must still discuss your results, possible reasons for differences, reasons your data may or may not follow the expected outcome, etc.  Include any experimental situations that may have affected the data.


      Use the style of your choice. Make sure that any web citations include author name and date.

    • FOS 6355C Instrumental Analysis and Separations

      The following sections will be required for each experiment.  You will read over the lab handout BEFORE coming to do the lab exercise.  To ensure that you have looked over the handout, you will be required to have the Title, Introduction, and Procedures sections written into your lab book before you will be allowed to begin the experiment.

      • Title of the Experiment:
      • Introduction & Purpose:  Summarize the introduction supplied to you in the lab handout.  This is required before beginning the lab and will be checked by the lab instructor.
      • Procedure:  Summarize the procedures section from the lab handout.  This is required before beginning the lab and will be checked by the lab instructor.
        Chemicals & Instrumentation:  If standards or reagents are to be prepared, note how they were made up and what quantities were used.  Record the make and model of all instruments used.  Record the manufacturer and stationary phase type on all chromatography columns.  Record the experimental conditions such as mobile phase gradients, oven temperatures, and integrator settings such as chart speed, attenuation, and peak sensitivity.  Note any modifications that are made to the standard conditions or procedures.
      • Results, Observations & Ideas for Further Experiments:
        Plan ahead so that the data can be recorded in a logical and easy to read format.  Leave space to insert any important graphs, charts, or chromatograms.  You do not need to insert copies of every chromatogram, but insert enough to illustrate important differences in the data.  Make sure that all results are clearly correlated with the specific set of conditions of from which the results are obtained.  If calculations are required, clearly show sample calculations including all units of measure in your notebook.  Repeated calculation can be performed using a spreadsheet or other computer software.  Include important computer printouts by taping or gluing them into your notebook. 
      1. All entries will be written in blue or black ink.  Do not use felt-tip pens or pencils.
      2. Errors will be crossed out with a single line and the correct entry added next to the crossed out entry.  It is not necessary to initial and date the corrections.
      3. Reserve the first 3 pages for the table of contents.  Keep the table of contents up to date by recording the title of the experiment and date it was begun.  If your lab notebook does not have page numbers, number the pages in the upper right hand corner.  Circle the page number or otherwise indicate that it is a page number and not part of your data!
      4. Each page in your notebook will be signed and dated by you after entries on that page are completed.
      5. If you wish to begin a new section, insert a large table, or begin a new experiment on a new page without completely filling the previous page, make a diagonal line across the  blank section of the page to indicate that no additional information is to be recorded there.
      6. Chromatograms or other computer output (such as graphs of standard curves made in  Excel) should be taped into the notebook in an appropriate place.  All lab partners will need to insert the required chromatographs so copies will have to be obtained.
      7. Generally you should not leave any blank pages in your notebook.  However, for this class you may leave a few blank pages at the end of an experiment for insertion of chromatographs etc. that make take time to copy.  After inserting all required chromatograms and you have blank pages left over, draw a diagonal line through the pages and sign and date them.  If you did not leave enough space for all of the required chromatograms or other experimental results, you can insert them later in the notebook but be sure to indicate that the results are continued and the page numbers where the additional results can be found.
      8. Have your lab partner sign your notebook after an experiment is completed.
