Correction to Determining the Extent of Biodegradation of Fuels Using the Diastereomers of Acyclic Isoprenoids Cameron P. McIntyre,* Paul McA. Harvey, Susan Ferguson, Anna M. Wressnig, Herbert Volk, Simon C. George, and Ian Snape Environ. Sci. Technol. 2007, 41, 2452−2458; DOI: 10.1021/es0621288. The retention time shown in Figure 1 is incorrect. In this case, the gas chromatograph was run using constant pressure conditions (25 psi) rather than with the constant flow conditions (1.2 mL/min) detailed in the methods section. As a result, the peaks eluted around 15 min later. Figure 2 shows the correct retention times for the constant flow method detailed in the methods section. Also, Figure S2 in the Supporting Information is correct and also shows the retention times when run with constant pressure conditions (25 psi), hence it has later eluting peaks as in Figure 1.
