The minimum detection limits using flame-emission spectroscopy with the nitrous oxide–acetylene flame and using atomic-absorption spectroscopy were determined under optimum instrumental and flame-operating conditions for 68 elements, using the same nebulizer system, the same instrument, and signal integration techniques. Based on these studies, 27 elements show equal detectability by the two methods, 15 are more sensitive by flame emission, and 26 are more sensitive by atomic absorption. Results are compared and discussed with respect to theoretical prediction.
