Correction The Detection of Nitro Pesticides in Mainstream and Sidestream Cigarette Smoke Using Electron Monochromator-Mass Spectrometry A. John Dane, Crystal D. Havey, and Kent J. Voorhees* (Anal. Chem. 2006, 78, 3227-3233).
An additional reference should have been included with ref 25 for the sentence “Flumetralin is a suspected endocrine disruptor that the European Commission has banned for use on tobacco.” The additional reference is Byrne, D. Official J. Eur. Communities 2002, L319/3-11. This reference includes the actual European Commission directive that banned flumetralin for general use as a plant protection product in the European Union.

Automated Sampling and Imaging of Analytes Separated on Thin-Layer Chromatography Plates Using Desorption Electrospray Ionization Mass Spectrometry Gary J. Van Berkel* and Vilmos Kertesz (Anal. Chem. 2006, 78, 4938-4944)
In the third sentence of the first paragraph of the Experimental Section, the concentration of the analytes spotted on the TLC plates was actually 200 ng/µL, not 0.2 ng/µL. This statement should have read, “Standard stock solutions were prepared for TLC and ES-MS detection optimization by dissolving the dyes in methanol. A concentration of 200 ng/µL (450 pmol/µL for rhodamines B and 6G and 580 pmol/µL for rhodamine 123, respectively) was used for TLC spotting and a concentration of 0.2 ng/µL (450 fmol/µL for rhodamines B and 6G and 580 fmol/ µL for rhodamine 123, respectively) was used for ES-MS optimization.” The fifth sentence of the section, Spot Sampling of Separated Analyte Bands on a TLC Plate, should have read, “Spotted in lanes 1, 2, and 3, respectively, were 200 ng of rhodamine B (1), rhodamine 6G (2), and rhodamine 123 (3)”, rather than “...200 pg...”. Note that all figure headings indicating that 200 ng of the dyes was spotted on the TLC plates is correct. AC061299S 10.1021/ac061299s Published on Web 08/09/2006
