4F - H2O Total

A 0.3 g sample is thermally decomposed in a resistance furnace in a pure nitrogen environment at 1000 °C, using an ELTRA CW-800, directly releasing H2O, which includes both H2O- and H2O+. H2O absorbs IR energy at a precise wavelength within the IR spectrum. Energy from the IR source is absorbed as the gas passes through the cell; preventing it from reaching the IR detector. All other IR energy is prevented from reaching the IR detector by a narrow bandpass filter. Because of the filter, the absorption of IR energy can be attributed only to water (H2O). The concentration of H2Ois detected as a reduction in the level of energy at the detector.
