Abstract：The Peltier-cooled spray chamber is a widely used device in inductively coupled plasma mass spectrometer (ICP-MS), and it can improve the analytical performance of the instrument. The self-developed Peltier-cooled device was applied to the domestic inductively coupled plasma quadrupole rod mass spectrometer. 9Be, 89Y, 115In, 138Ba, 140Ce, and 209Bi, which covered the low, moderate and high mass-to-charge ratio, were selected as the object of study. The effect of spray chamber temperature in range of 0-20 ℃ on the background noise, limit of detection, signal intensity, oxide yield, and yield of doubly-charged ions was investigated. The results showed that after using the Peltier-cooled device, as the spray chamber temperature decreased, the background noise at 9Be, 115In, and 209Bi decreased by 51%, 54%, and 29%, respectively. The limit of detection exhibited different trends with the decrease of spray chamber temperature: the limit of detection for 9Be decreased, while the limits of detection for 115In and 209Bi fluctuated at a low level. When the flow rate of carrier gas was low, the signal intensity decreased with the decrease of spray chamber temperature. When the flow rate of carrier gas was high, the reducing range of signal intensity decreased with the decrease of spray chamber temperature, or the signal intensity increased. After turning on the refrigeration, the water entering into the plasma decreased, and the oxide yields of 138Ba and 140Ce decreased by 23% and 31%, respectively. Less water led to the increase of plasma temperature, and the yields of double-charged ions increased by 16% and 15%, respectively.
