Surface plasmon resonance (SPR) has become an important optical biosensing technology in the areas of biochemistry, biology, and medical sciences because of its real-time, label-free, and noninvasive nature. The high cost of commercial devices and consumables has prevented SPR from being introduced in the undergraduate laboratory. Here, we present…

A simulation game is used to teach students in instrumental analysis courses to find the latest developments in the field, use the journal literature, and apply critical thinking to determine the relative importance of the work they find. They also learn about the business of chemical instruments and to make oral presentations. The competitive…

The drooping mercury electrode (DME) was previously used to carry out electrochemical experiments but invention of polarography technique changed this. Voltammetry with DME was given the term polarography and are used in measurement of current as a function of potential at small electrodes.

Princeton Applied Research Corporation (PAR) was a small electronic instrument company in early 1960s but once they entered electrochemistry they were very successful. Since then they have developed and designed successful instruments with their tremendous knowledge and have made great contribution to the field of analytical chemistry.

The construction of a fluorometer and a spectrofluorometer using flashlight or a sunlight excitation source in a shoebox and the eye as a detector is being described. The assembly helps in understanding several fundamental ideas related to the subject very easily.

Electrochemistry, which combines chemistry and electronics, is an exciting field and those who are in this field are very versatile scientists. Electrochemistry is a combination of true phenomena and an instrument to teach much about other fields and its technological advances touch many other fields as well.

The evolution of Raman instrumentation from the time of the initial report of the phenomenon in 1928 to 2006 is discussed. The first instruments were prism-based spectrographs using lenses for collimation and focusing and the 21st century instruments are also spectrographs, but they use CCD cameras. The Lippmann filter technology that appears to…

The fundamentals, as well as the instrumentation of the quartz-crystal microbalance (QCM) technique that is used in an undergraduate laboratory experiment are being described. The QCM response can be easily used to change the properties of any system.

The construction of a new highly-sensitive, computer-interfaced, differential thermal analysis (DTA) device, used for gathering different information about the chemical reactions, is described. The instrument provides a better understanding about the phase transitions, phase diagrams and many more concepts to the students.

This is the second of two reviews dealing with analytical methods applicable to environmental chemistry. Methods are discussed under gas, liquid, or solid depending upon the state of the analyte during detection. (RH)

A unifying modular approach to the description of modern instrumentation used in analytical measurements is described. Through the identification of five modules for analytical instrument, discussions pertaining to the different physical and chemical interactions can be better directed towards the similarities and differences in the actual methods.

Note is presented on the standard lab from a second year chemistry course. The lab "Determining which of the Seven FD&C Food-Approved Dyes are Used in Making Green Skittles", familiarizes students with the operation of the CHEM2000 UV-Vis spectrophorometer.

A study of the development of commercial electron spectroscopy of chemical analysis (ESCA) instrumentation over a span of three decades is presented. The field has also been extended significantly by use of synchrotron radiation as a bright X-ray source, which has opened new areas of research in solid-state physics, molecular biology, and many…
