1. A method for controlling total oxygenate content of a composition that comprises at least 1% by volume of oxygenate content, comprising in combination the steps:

  • a. measuring the value of at least one absorbance in at least one wavelength between about 1,300 to1,350 nanometers; and

    b. substituting said value into an equation to obtain a prediction of oxygenate content of said composition, whereby the effect of temperature on said prediction is reduced; and

    c. controlling said composition in response to said prediction.
