以实践为依据,设计和研制了一种新的LB型雾化型。它是高盐含量和高效的玻璃同心雾化器。这种雾化器对于高达NaCl饱和含量溶液(25℃时为26.54%)长时间并连续操作不会堵塞是有能力的。同时,载气流量和溶液提升速率保持不变。在测定Zn,Co,Cd,Ni,Cu和Zr各5ppm的溶液时,波动系数大部份小于0.5%。这种雾化器与通常使用的玻璃同心雾化器比较,具有更高的信噪比和更低的检出限,尤其对稀土元素分析,效果更佳。
Based on practice, a new type of LB atomization was designed and developed. It is a concentric glass atomizer with high salt content and high efficiency. This nebulizer is capable of up to a saturation content of NaCl solution (26.54% at 25 ° C) for a long time and will not clog up continuously. At the same time, the carrier gas flow rate and solution lift rate remain unchanged. In the determination of Zn, Co, Cd, Ni, Cu and Zr each 5ppm solution, most of the volatility coefficient of less than 0.5%. Compared with the commonly used glass concentric nebulizer, this nebulizer has higher signal-to-noise ratio and lower detection limit, especially for rare earth element analysis.
