FAB-MS is used to accurately quantitate surfactants from aqueous environmental matrices with minimal sample prep aration. A low-resolution, full-scan method and a higher resolution continuum acquisition technique are compared with an HPLC approach for surfactant quantitation. J. R. Simms and T. Keough*, The Procter & Gamble Company, Miami Valley Laboratories, P.O. Box 398707, Cincinnati, OH 45239-8707, and S. R. Ward, B. L. Moore, and M. M. Bandurraga, The Procter & Gamble Company, Ivorydale Technical Center, 5299 Spring Grove Avenue, Cincinnati, OH 45217 Anal. Chem., 60 (1988) Inclusion Complex Formation of Benzo[a]pyrene Metabolites with Cyclodextrins 2621 The feasibility of using HPLC methodologies with cyclodex trins as stationary or mobile media separating benzo[a]pyrene metabolites is assessed by spectroscopic binding studies and some HPLC measurements. Rudyea Woodberry, Sharon Ransom, and Fu-Ming Chen*, De partment of Chemistry, Tennessee State University, Nashville, TN 37209-1561 Anal. Chem., 60 (1988) On-Line Connector for Microcolumns: Application to the OnColumn o-Phthaldialdehyde Derivatization of Amino Acids Separated by Capillary Zone Electrophoresis 2625 Construction of a connector with negligible dead volume is described for microcolumns. Its utility is illustrated by the ΟΡΑ derivatization of amino acids following separation by capillary zone electrophoresis. Stephen L. Pentoney, Jr., Xiaohua Huang, Dean S. Burgi, and Richard N. Zare*, Department of Chemistry, Stanford University, Stanford, CA 94305 Anal. Chem., 60 (1988) Comparison between Experimental and Theoretical Band Profiles in Nonlinear Liquid Chromatography with a Pure Mobile Phase 2630 The theory of nonlinear chromatography permits the accu rate prediction of the profiles of large concentration bands, provided an exact expression of the equilibrium isotherm of the studied compounds is available. Sadroddin Golshan-Shirazi, Samir Ghodbane, and Georges Guiochon*, Department of Chemistry, University of Tennessee, Knoxville, TN 37966-1600, and Division of Analytical Chemistry, Oak Ridge National Laboratory, Oak Ridge, TN 37831 Anal. Chem., 60 (1988) Comparison between Experimental and Theoretical Band Profiles in Nonlinear Liquid Chromatography with a Binary Mobile Phase 2634 The theory of nonlinear chromatography permits the accu rate prediction of the profiles of large concentration bands eluted with a binary mobile phase if the strong solvent is much less strongly sorbed than the solute studied. Sadroddin Golshan-Shirazi and Georges Guiochon*, Depart ment of Chemistry, University of Tennessee, Knoxville, TN 379661600, and Division of Analytical Chemistry, Oak Ridge National Laboratory, Oak Ridge, TN 37831 Anal.
