Laboratories submitting experimental results to the Food and Drug Administration (FDA) or the Environmental Protection Agency (EPA) in support of Good Laboratory Practice (GLP) nonclinical laboratory studies must conduct such work in compliance with the GLP regulations. To consistently meet these requirements, lab managers employ a "divide…

In this article we report on the use of a graduate "Special Topics" course to provide vital research and practical laboratory experience, within the context of developing a chemical process to manufacture biodiesel from algal sources. This course contained several key components that we believe are necessary skills in graduate research: 1) a…

The experiments in this manual represent state-of-the-art techniques which should be within the budgetary constraints of a college physics or chemistry department. There are fourteen experiments divided into five modules. The modules are on X-ray fluorescence, charged particle detection, neutron activation analysis, X-ray attenuation, and…

Six short papers are presented on analytical chemistry in an integrated laboratory sequence, analytical chemistry at a junior college, the sophomore level analytical laboratory, the analytical textbook situation, and graduate level analytical chemistry. (BB)

Reviewed is the use of the Thin-Film Mercury Electrode for anodic stripping voltammetry, simple voltammetry of solution cations and cathodic stripping voltammetry for the determination of an environmentally important molecule, thiourea. The construction of a simple potentiostat and applications for student laboratory courses are included. (CW)

Discussed is some of the confusion encountered in electrochemistry due to misunderstandings of sign conventions and simple mathematical errors. Clarified are issues involving emf series, IUPAC sign conventions, calculation of cell potentials, reference electrodes, the polarity of electrodes in electrochemical devices, and overpotential. (CW)

Described is the separation of dyes using a conventional liquid chromatographic pump and a glass column. Included are the preparation of the column and dye separations. (CW)

Described is an undergraduate coordination chemistry experiment that enables students to relate concepts developed in class about the stereochemistry and coordination numbers to the interpretation of the electronic and infrared spectra and their magnetic behavior. Indicates that thermal decomposition and x-ray diffraction studies can also be…

Describes an analytical technique termed the "thermostatic method" that is both conceptually and operationally simple and does not require the removal of liquid samples for analysis. Presents the theoretical background, experimental procedures, and analysis of results. (CW)

Proposes a series of experiments that integrate analytical techniques in order that students are able to compare, based on their laboratory results, the relative reliabilities of the most common therapeutic drug monitoring methods. Discusses materials, procedures, and results of three experiments on the determination of drug concentration by…

Describes a simple, inexpensive experiment in which students determine the heats of combustion of common solid, liquid, and gaseous fuels. The experimental apparatus, procedures, calculations and results are discussed. (CW)

Explains that triglycerides consist of a mixture of different compounds, depending on the total number of fatty acid constituents. Details the method and instrumentation necessary for students to analyze a vegetable oil for its triglyceride content. Describes sample results. (CW)

Describes a purification process through affinity chromatography necessary to obtain specific blood group glycoproteins from erythrocytic membranes. Discusses the preparation of erythrocytic membranes, extraction of glycoprotein from membranes, affinity chromatography purification, determination of glycoproteins, and results. (CW)

Classroom discussion of scientific articles can be an effective means of teaching scientific principles and methodology to both undergraduate and graduate science students. The availability of classic papers from the American Physiological Society Legacy Project has made it possible to access articles dating back to the early portions of the 20th…

Reported are the results of a survey conducted to identify which analytical methods are most commonly used in nonacademic analytical laboratories. Laboratory supervisors' ratings of various aspects of chemical education are included. (CW)
