Labs

Spectrophotometric pKa

• Experiment
  • pKa of an Indicator by UV-Visible Spectrophotometry
• Instrument Information and Operator's manuals
  • Student Instructions for Agilent 8453 UV-Visible Spectrophotometer
    • A copy of this one-page guide is in the lab next to the instrument.
  • Agilent UV-vis 8453 manual (complete manual from Agilent)
  • Temperature Controller for Agilent 845

Atomic Absorption

• Experiment
  • Atomic Absorption Determinations
• Instrumentation
  • Student Instructions for Operating the Perkin-Elmer 3110 Atomic Absorption Spectrophotometer

Fluorescence

• Experiment
  • Fluorescence and Determination of Quinine.
• Instrumentation
  • Cary Eclipse Instructions

Gas Chromatography I. Retention and Efficiency.

• Experiment
  • Gas Chromatography I
• Instrumentation
  • Student Instructions for Operating the Agilent 6850 GC
• Additional Resources
  • Diffusion Coefficients for Binary Gas Systems. Excerpt from book by R. C. Reid, J. M. Prausnitz and B. E Poling, The Properties of Gases and Liquids, 4th ed., McGraw-Hill, 1987. To calculate the reduced velocity in GC, you need an estimate of the diffusion coefficient. The empirical calculation by Fuller et al is discussed in Section 11-4, pages 586-589. Background information on the nature of the diffusion coefficient begins on page 580.

GC/MS Analysis of Kerosene

• Experiment
  • GC/MS Analysis of Kerosene
• Instrumentation
  • Student Instructions for the Hewlett-Packard GC/MS System
• Theory
  • Lab Prep Notes on GC/MS (ppt)

HPLC

• Experiment
  • Method Development in HPLC. Determination of Additives in Cola Drinks.

Cyclic Voltammetry

• Experiment
  • Voltammetry at Stationary and Rotated Electrodes

Ion Selective Electrode Measurements

• Experiment
  • Response of the Calcium Ion-Selective Electrode

Capillary Electrophoresis of Organic Acids

• Experiment
  • Separation of Organic Acids by Capillary Electrophoresis
• Instrumentation
  • Operation of the Beckman P/ACE 5000 Capillary Electrophoresis System
• Additional Resources
  • Introduction to Capillary Electrophoresis, Beckman Instruments, Inc., 1991. Excerpts from the Beckman publication. This is a nice, breif introduction to the theory and practice of CE.
  • Article from the Journal of Chromatography Hsieh and Chang, 1998, on which this experiment is based.
