摘要：
A new automatic sample solution introduction system for miniature simultaneous microwave plasma torch( MPT) atomic emission spectrometer was developed. The operating parameters were optimized. The detection limits of the spectrometer with an ultrasonic nebulizer for Ag, Al, Ba, Ca, Cr, Cu, Fe, Mg, Mn, Sr, and V are 5-10 times lower than those obtained with a pneumatic nebulizer and are also lower than those obtained by a Model JX-1010 MPT spectrometer. Two practical samples were analyzed to test the reliability and sensitivity of the system.
