A previous part (Analytical Chemistry; v57 n9 p1057A) discussed the theoretical aspects of diode ultraviolet-visual (UV-VIS) spectroscopy. This part describes the applications of diode arrays in analytical chemistry, also considering spectroelectrochemistry, high performance liquid chromatography (HPLC), HPLC data processing, stopped flow, and…

Reviews various spectroscopic techniques currently used to analyze real physical surfaces that bound two actual phases. Problems inherent in analyzing these surfaces and possible approaches that may be taken are considered. (JN)

The 38th Annual Summer Symposium on Analytical Chemistry (June 18-20, 1985) focused on the surface characterization of catalytic and electronic materials. Highlights of the symposium are provided, including presentations that considered lasers and microscopy. (JN)

Describes methods for isolating, purifying, and analyzing plant hormones (molecules involved in plant growth regulation and development). The presentation reflects the historical development of analyses, beginning with bioassays and ending with novel immunochemical assays. (JN)

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)

Examines recent developments in techniques for obtaining high-resolution nuclear magnetic resonance (NMR) spectra on solid samples, discussing the kinds of applications for which these techniques are well suited. Also discusses the characteristics of NMR of solids and generating magnetization for NMR in solids. (JN)

The fundamentals of two surface techniques--secondary-ion mass spectrometry (SIMS) and ion-scattering spectrometry (ISS)--are discussed. Examples of how these techniques have been applied to surface problems are provided. (JN)

Described are some new uses and procedures of titration procedures. Topics included are titration in non-aqueous solvents, thermometric titration and catalytic methods for end-point detection, titration finish in organic elemental analysis, and sub-micro analysis and automatic titration procedures. (CS)

Described are infrared windows made from Tupperware and polyethylene coffee can lids that provide acceptable spectra for low-frequency infrared. (RH)

Described is a quick, easy, and cheap, but effective method of obtaining infrared spectra of solids and nonvolatile liquids by Fourier transform infrared spectroscopy. The technique uses tissue paper as a support matrix. (RH)

Described is an alternative method to infrared spectroscopy for the quantification of xylene mixtures. The method employs nuclear magnetic resonance spectroscopy. (RH)

Described is an experiment to investigate the plasticizer content in polyvinyl chloride (PVC) products. The experiment is designed for college students using an instrumental analysis laboratory. (RH)

Discusses problems and prospects in: (1) multielement atomic adsorption spectroscopy (AAS); (2) inductively coupled plasma (ICP) atomic emission; and (3) other aspects of atomic spectrometry. (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…
