Limitations in Analytical Accuracy, Part I: Horwitz's Trumpet
September 2006. In the first part of this two-part series, columnists Jerome Workman, Jr. and Howard Mark discuss the limitations of analytical accuracy and uncertainty.
September 2006. An unusual form of spectroscopy uses light and sound to probe the behavior of materials. Here is a brief introduction to photoacoustic spectroscopy.
33rd Annual FACSS Meeting
September 2006. Spectroscopy previews the 33rd Annual Meeting of the FACSS, to be held September 24-28 in Lake Buena Vista, Florida.
Market Profile: Double-Beam UV-Vis Spectrophotometers
Double-beam UV–Vis spectrophotometers include the most advanced instruments in the UV–Vis market today. They allow more rapid and greatly simplified UV–Vis analyses for users. The market for double-beam UV–Vis instruments is dominated by the major diversified scientific instrument manufacturers.
Chemically Selective Imaging with Broadband CARS Microscopy
September 2006. The authors rapidly acquire complete vibrational spectra in the fingerprint region using a single femtosecond laser for broadband coherent anti-Stokes Raman scattering (CARS) microscopy to image spatially variant compositions of condensed-phase samples.
New Developments in Wavelength-Dispersive XRF and XRD for the Analysis of Foodstuffs and Pharmaceutical Materials
September 2006. The authors discuss the benefits of X-ray fluorescence (XRF) for the determination of elemental nutrients in foodstuffs and X-ray diffraction (XRD) for the measurement and characterization of different compounds used in the pharmaceuticals industry.
