“…4, includes an acoustic reflector consisting of two parabolic mirrors. The reflector is analogous to the one proposed by Carrer et al 48 The laser beam axis coincides with the focal axis of the first mirror ͑translation paraboloid͒ with a focal distance of 0.01 m and length of 0.15 m. It changes the cylindrical acoustic wavefront generated by the light absorption into the plane wavefront. The opposite mirror is a rotation paraboloid that focuses the plane wavefront on the 1 / 2 in.…”

The method of time-resolved photoacoustic spectroscopy is applied to study the weak aerosol absorption of shortwave radiation in the atmospheric air. Using synchronous measurements of aerosol light absorption coefficients by a pulsed photoacoustic spectrometer and mass concentration of black carbon by an Aethalometer, we determine the values of the efficiency of aerosol light absorption in the atmospheric air in the shortwave spectral range for three wavelengths: ͑0.532 m͒ = ͑5.49± 3.57͒m 2 g −1 ,͑0.694 m͒ = ͑4.46± 2.61͒m 2 g −1 , and ͑1.064 m͒ = ͑2.87± 1.84͒m 2 g −1 . The experimental results are approximated by the spectral dependence ͑͒ = 3.1 −0.92 , where wavelength is expressed in micrometers. We discuss the calibration procedure for the pulsed photoacoustic spectrometer in studying the aerosol absorption.

“…A fountain cell, constructed for flow injection analysis, exploits radial flow to produce a thin disk-shaped detection volume with a large surface area (371). Two sandwich-type fiber-optic flow-through cells were compared in regard to their performance for absorption detection (372), and new cell designs for specialized applications of photoacoustic spectrometry continue to be published (373)(374)(375)).…”

This review reports the developments in ultraviolet and light absorption spectrometry from January 1992 through December 1993, primarily as documented in the Ultraviolet & Visible Spectroscopy section of CA Selects, and extends the series of reviews on these topics sponsored by Analytical Chemistry starting with Light Absorption Spectrometry in 1945 (1-3), followed by Ultraviolet Absorption Spectrometry in 1949 (4-9) and combined Ultraviolet and Light Absorption Spectrometry in 1978 (10, II). The format of this review follows that of its recent predecessors, with the subject matter divided into sections on chemistry, physics, and applications.The applications section is comprised of tables which summarize the routine determinations of inorganic and organic substances. The literature on ultraviolet and light absorption spectrometry continues to be so extensive and varied in scope that citations in this review are limited to those developments which the authors believe are of greatest interest to analytical chemists and those engaged in the chemical analysis of materials. Asa result of this necessary selectivity, the authors apologize in advance for any errors of judgement made in the omission of specific citations.It is with great sadness that this year's review must report on the death of the founder of this review series and a giant in the development of analytical chemistry as a discipline, Melvin Guy Mellon. Professor Mellon died September 6, 1993, at the age of 99. He authored or coauthored with his former student. Professor David Boltz, the first 17 review articles on Light Absorption Spectrometry, starting in 1945.
