Molecular emission cavity analysis has been used to determine soluble sulfate in soil [69]. [Pg.167]

Selenium cannot be usefully determined by flame AES techniques, because of the high excitation energy associated with its low-wavelength resonance lines. However, it has been shown that it can be determined by a cool flame, molecular emission cavity analysis technique, as discussed briefly in Chapter 2, section 13. [Pg.89]

Emission spectrometry using chemical flames (flame atomic emission spectrometry, FAES) as excitation sources is the earlier counterpart to flame atomic absorption spectrometry. In this context emission techniques involving arc/spark and direct or inductively coupled plasma for excitation are omitted and treated separately. Other terms used for this technique include optical emission, flame emission, flame photometry, atomic emission, and this technique could encompass molecular emission, graphite furnace atomic emission and molecular emission cavity analysis (MEGA).

Molecular emission cavity analysis (MECA) is a flame chemiluminescence technique based on the generation of excited molecules, radicals, or atoms within a hydrogen diffusion flame. The excited species are formed by direct or indirect chemiluminescence mechanisms and are confined within the inner space of a small cavity, which is positioned at a preselected point of the flame environment. The emission is monitored at the characteristic wavelength of... [Pg.3199]

Electrode materials of electrochemical cells have been analyzed by a method in which free sulfur is first isolated from the sample by solvent extraction and then determined by molecular emission cavity analysis. The lowest limit of detection for free sulfur that can be analyzed is 0.8 pg per g. [Pg.4568]
