Numerous editorial and minor technical errors require correction: 9.3.3: isobutene is the same as isobutylene. It should read isobutane. 12.1: Calculations are used for all components, not specific for hydrocarbons only. Equation 5 was written incorrectly. The operator should be multiply, not divide. Table 1: The table displays all components, not only hydrocarbons Figure 1: One peak is incorrectly labeled argon/nitrogen. The correct label is argon/oxygen. Appendix X1: The Fahrenheit equivalent of 10C/min is 18F/min, not 50F/min. Makeup gas flow, column flow rates, and column linear velocity do not apply to thermal conductivity detectors and packed columns. This information should be removed.
