Discusses the need to encourage increasing numbers of persons to enter analytical chemistry, educate them thoroughly in basic chemical science, and expose them to the most modern methods and instrumentation. Examines some problems and several university's efforts to overcome them. (MVL)

Discusses two surface techniques: X-ray photoelectron spectroscopy (ESCA) and Auger electron spectroscopy (AES). Focuses on fundamental aspects of each technique, important features of instrumentation, and some examples of how ESCA and AES have been applied to analytical surface problems. (JN)

Presents two lists: (1) important considerations for any total chemical analysis and (2) a condensed version that can be used by students to evaluate each analytical procedure. Benefits of using the condensed version (such as seeing that instrumentation is only one of several components of an analysis) are noted. (JN)

Software-driven instrumentation makes measurements that demand a computer as an integral part of either control, data acquisition, or data reduction. The structure of such instrumentation, hardware requirements, and software requirements are discussed. Examples of software-driven instrumentation (such as wavelength-modulated continuum source…

The basic principles, current techniques, instrumentation, and possible chemical applications of nuclear magnetic resonance (NMR) imaging are discussed. (JN)

Discusses two applications of Laboratory Information Management Systems (LIMS) in the undergraduate laboratory. They are the coulometric titration of thiosulfate with electrogenerated triiodide ion and the atomic absorption determination of calcium using both analytical calibration curve and standard addition methods. (JN)

Provides an overview of Laboratory Information Management Systems (LIMS) and their implementation in undergraduate analytical laboratories. Basic components of a well-constructed LIMS system, hardware considerations, and software considerations are addressed. (JN)

A technician auto analyzer (consisting of six modules: sampler, multichannel peristaltic pump, dialyser, heating/incubation bath, colorimeter, and recorder) was modified by using key modules and substituting standard equipment for others; spectronic 20 with homemade flow cell for colorimeter module. Descriptions and diagrams of the apparatus are…

Describes an experiment for recording two individual spectrophotometer response curves. The two curves are directly related to the power of transmitted beams that pass through a solvent and solution. An absorption spectrum of the solution can be constructed from the calculated rations of the curves as a function of wavelength. (JN)

Laser enhanced ionization (LEI) occurs when a tunable dye laser is used to excite a specific atomic population in a flame. Explores the origin of LEI's high sensitivity and identifies possible avenues to higher sensitivity by describing instrument used and experimental procedures and discussing ion formation/detection. (Author/JN)

Discusses major themes and interrelationships common to bioselective potentiometric membrane electrodes including the nature of bioselective electrodes, applications, and future prospects. Includes tables on traditional ion-selective membrane electrodes, nontraditional electrodes, and typical biocatalytic potentiometric electrodes. (Author/JN)

Some of the important modern developments of thin-layer chromatography are introduced. Discussed are the theory and instrumentation of thin-layer chromatography including multidimensional and multimodal techniques. Lists 53 references. (CW)

Major instrumental concerns in molecular solution fluorimetry have recently turned away from sensitivity enhancement to an orientation more directed toward selectivity. This trend simply recognizes that such methodology has historically been blank limited. Thus, the described uses of liquid chromatography, line narrowing, and time resolution…

Describes laboratory workstations which provide direct connection for monitoring and control of analytical instruments such as pH meters, spectrophotometers, temperature, and chromatographic instruments. This is accomplished through analog/digital and digital/analog converters for analog signals and input/output devices for on/off signals.…

Describes interactive, computer-graphics program emulating behavior of high resolution, ultraviolet-visible analog recording spectrophotometer. Graphics terminal behaves as recording absorption spectrophotometer. Objective of the emulation is study of optimization of the instrument to yield accurate absorption spectra, including…
