Emission line spectrum for mercury vapor lamp
WebEmission line spectrum. Do mercury vapor lamps emit UV light? Under normal operating conditions mercury vapor lamps provide efficient, long-lasting sources of light. However, if the outer bulb breaks, and the inner tube continues to produce unshielded light, intense UV radiation is emitted. Are mercury vapor lights banned? WebThe calibration curve was plotted with the concentration of mercury ranging from 0.5 ng mL −1 to 1000 ng mL −1, with a correlation coefficient > 0.99 and the limit of detection of 0.03 ng mL −1. Two certified reference materials were analyzed, and a t-test demonstrated that the determined results by the proposed method had no significant ...
