Abstract: In this paper, a novel low microwave-powered thermospray system was developed. In this system the focused microwave oven used in traditional microwave-powered thermospray nebulizer was replaced with a TM010microwave resonant cavity, the high pressure pump was replaced with a peristaltic pump. This improvement makes the thermospray system more compact and economical. The influence of several experimental variables(concentration of acid, sample uptake rate, carrier flow rate) on the emission intensity of Mg was evaluated. Compared with the pneumatic nebulization, the detection limits for Mg of this system was improved by a factor of 4.
