A flame test is an analytic procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic emission spectrum.lthough the flame test only gives qualitative information, not quantitative data about the proportion of elements in the sample, quantitative data can be obtained by the related techniques of flame photometry or flame emission spectroscopy. Flame Atomic absorption spectroscopy Instruments, made by e.g.
The flame test carried out on a copper halide. The characteristic bluish-green color of the flame is due to the copper. Different flame types of Bunsen Burner depending on air flow through the valve: 1. air valve closed. 2. air valve nearly fully closed. 3. air valve semi-opened. 4. air valve maximally opened.lthough the flame test only gives qualitative information, not quantitative data about the proportion of elements in the sample, quantitative data can be obtained by the related techniques of flame photometry or flame emission spectroscopy.
