A laminar flow premixed oxygen-hydrogen flame when combined with ultrasonic nebulization has improved detection limits approaching three orders of magnitude when compared to a conventional turbulent oxygen-hydrogen flame used in flame emission spectrometry. In a comparison with two other premixed flames, the premixed oxygen-hydrogen flame gave the lowest detection limits for elements with wavelengths longer than 4000 A. The increased sensitivity is attributed to the low flame background emission and reduced flame flicker. Modified author abstract
