研究了产生记忆效应的原因及其消除方法,研制了水冷式加热雾化室。该雾化室分冷却区和加热区,保持雾化器喷嘴处于室温状态,既有效地降低了检出限,又减少了记忆效应。
The reason of producing memory effect and its elimination method are studied, and a water-cooled heated atomization chamber is developed. The atomization chamber is divided into a cooling zone and a heating zone to keep the atomizer nozzle at room temperature, thereby effectively reducing the detection limit and reducing the memory effect.
