CORRECTIONS Thermal Lens Spectrophotometry with Argon Laser Excitation Source for Nitrogen Dioxide Determination Tatsuji Higashi, Totaro Imasaka, and Nobuhiko Ishibashi (Anal. Chem. 1983,55,1907-1910). On page 1908 eq 2 and 5 should be

On page 1908, line 22, the relative value to the old enhancement factor should be 0.524 instead of 0.227. On page 1910, line 14, the calculated enhancement should be 26.0 instead of 11.3.
Temperature Dependence and Measurement of Resistivity of Pure Water Truman S. Light (Anal. Chem. 1984,56,1138-1142). Equation 8 on p 1141 should read
LX = Ls(Rx/Rs) (cm-9 Determination of Microgram Amounts of Selenium and Tellurium in Copper-Base Alloys by Atomic Absorption Spectrometry Michael Bedrossian (Anal. Chem. 1984,56, 311-312). There is an unfortunate error in the Procedure section, appearing on page 311. The standard calibration solutions should read 0.00, 25.0, 50.0, and 75.0 pg of selenium and tellurium, instead of 0.00, 25.0, 5.0, 75.0, and 100.0 mg of selenium and tellurium.
