Quantitative Effects of an Absorbing Matrix on Near-Infrared Diffuse Reflectance Spectra 2427 N e a r - I R diffuse reflectance s p e c t r a obey t h e K u b e l k a Munk law if the matrix does not absorb. T h e spectra follow Beer's law more closely if the matrix absorbs strongly. Rea sons for this behavior are proposed. Jill M. Olinger and Peter R. Griffiths*, Department of Chemis try, University of California, Riverside, CA 92521 Anal. Chem., 60 (1988) You expect it from B&J solvents. Now get it from B&J HPLC columns, too! Here's why: • Every column is tested to meet B&J performance standards. • Test chromatogram and benchmark standard are included with each column. • For more details contact Baxter Healthcare Corporation, Burdick& Jackson Division.
