Using exposition, graphics, and commercial videos, this module teaches the theory and application of affinity chromatography in the characterization of proteins, nucleic acids, and other biochemical/biomedical systems. Problems and application examples support the tutorial material.
Analytical Electrochemistry: Basic concepts
This module focuses on the basic concepts involved in dynamic electrochemistry when the net current is not zero - the combination of mass transfer and electrochemical reactions at the interface between solids and fluids. It is at an introductory level appropriate for undergraduates in their sophomore or junior years.
Adopting POGIL Methodology for Analytical Chemistry
POGIL (Process Oriented Guided Inquiry Learning) is a NSF sponsored project designed to actively engage students in the learning process in the classroom. Ana-POGIL activities cover topics ranging from statistics to equilibria and to instrumentation. Materials are intended to have students work in groups on activities; each activity is structured in such a way that each concept is divided into a series of leading questions that allow the team to work through the concept. Answer keys can be re
RSC.org: UV/Vis Spectroscopy
This video distributed on YouTube is on the basic principles of UV/Vis. Provides a good primer (~5 min), and the top-off look of the instrument is useful in explaining components. A double beam instrument is described.
RSC.org: IR Spectroscopy
This video on YouTube covers the basic principles of infrared spectroscopy. Very useful for a newcomer to IR. This video of 6.5 minute would be useful in a classroom setting or students interested in the technique.
RSC.org: Proton NMR
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of NMR. This video is a good primer and would be very useful to supplement introductory lectures on NMR. The video covers the basic theory behind a 1H spectrum and goes through actually acquiring a spectrum. The top-off look of the instrument is useful and how the superconducting magnet is mounted. Good for a basic introduction.
RSC.org: Mass Spectrometry
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of mass spectrometry, using a magnetic sector instrument to demonstrate how specific m/z ratios can be selected. The theory and operation of MS, including the chemistry of ionization and fragmentation is described at an introductory level. There\'s also an excellent example of the use of high resolution MS to differentiate between nominal mass and actual mass. The video does a very good job of explain
Veeco's Nanotheater provides over 350 images of surfaces acquired using atomic force microscopy and scanning probe microscopy. Images come from a wide variety of samples, including polymers, biologicals such as bacteria, and inorganic crystals. Many of the images contains brief descriptions of what is being shown, although the information is not particularly in-depth. Additional information on atomic force microscopy and scanning probe microcopy, including useful guides and animations, is availa
This pair of pH calculation programs serves as an excellent tool for anyone wishing to calculate the pH of a solution containing multiple acids and bases. These programs allow practitioners to predict the pH of simple and complex acid/base solutions and buffers. Users are encouraged to carefully read the guides provided by the author.
Animations and Simulations in the Teaching of Analytical Sciences
This article by Cynthia Larive, published in the \"ABCs of Teaching Analytical Science\" series of the journal Analytical and Bioanalytical Chemistry, will be of interest to faculty members teaching courses in the analytical sciences. The article provides a good introduction to the animations, simulations, and other on-line resources available on the internet. More important, it encourages instructors to develop a teaching philosophy that emphasizes the use of these materials.
A Primer on Scanning Tunneling Microscopy (STM)
A video primer on STM by Prof. R. Reifenberger, Purdue University Nanotech Center. A thorough discussion of fundamentals followed by the technical barriers and implementations - excellent graphics illustrating principles and experimental results. Historical context is provided making presentation interesting. Should be viewed by anyone interested in surface analysis at atomic dimensions.
Population Genetics and Statistics
This website is part of the President\'s DNA Initiative and is devoted to past and current methods of macromolecules such as DNA. This website introduces the student to the subject of population genetics and stresses factors that can alter allele frequencies in a population and calculations associated with the Hardy-Weinberg principle. The student will learn to use acceptable statistical approaches to evaluating DNA data and how DNA databases are constructed and applied. This site is designed as
Gas Chromatography Video
This is a high quality video module demonstrating the basics of gas chromatography. Highlights include different GC instruments, detectors etc., as well as unique topics such as trouble shooting and interfacing the column that are not addressed in standard texts. This resource can be run (Shockwave Flash) from the home server or downloaded to your computer.
NMR of Paramagnetic Proteins
This site presents an overview of techniques used for structural elucidation of paramagnetic metalloproteins. The content is directed to the more advanced NMR user and would be suitable for an upper division or graduate level NMR class.
This website provides resources that can aid in the interpretation of NMR proton shifts, identification of IR features and mass loss identification in mass spectrometry. The original site is in German, but most (but not all) the content is translated on the English version of the site. From the left hand menu under Spektroskopei-Tools choose Wizards. From here you can enter a chemical shift in ppm and the NMR tool will identify likely protons and environments that could cause the shift. Enter a
Laboratory Orientation and Testing of Body Fluids and Tissues for Forensic Analysts
This web site is part of the President\'s DNA Initiative and is devoted to an overview of historical and contemporary techniques to characterize body tissues. The first part of the course covers basic laboratory procedures, safety requirements for laboratory personnel and emphasizes quality control and quality assurance in the laboratory. The second section deals with serological techniques for characterizing specimens such as saliva, semen, blood and urine Identification and individual utilizin
Handbook of Basic Atomic Spectroscopic Data
This National Institute of Standards and Technology (NIST)) site containing atomic spectroscopic reference data. Information can be accessed through a variety of means, such as an interactive periodic table and dropdown lists of elements organized by name or atomic number. Data available include isotope abundance, electron configuration, nuclear spin, magnetic moment, ionization energies, spectral line wavelengths and intensities, and energy level information. References are also given.
Cooperative Learning Structures
This website is an invaluable resource on cooperative learning. The site provides information on a number of cooperative learning techniques such as jigsaw, think-pair-share, etc. that faculty who are interested in active learning will find invaluable.
This site is a good freshman or sophomore level introduction to diffraction and its application to studying crystal structure. Because it\'s very visual and interactive, it engages the student. It\'s not mathematical enough for an upper level course. The basics of diffraction are covered with excellent interactive demos. Demos are great as a supplement but not as a stand alone module on diffraction.
The site demonstrates principles behind the operation of the interferometer in an FTIR spectrometer. Graphics and interactive movies are used. Examples start from a single wavelength and build to the superposition of multiple wavelengths. The connection between an interferogram and a frequency domain spectrum is discussed.
