将玻璃同心雾化器与去溶装置联用,通过加入乙醇来提高进样效率。随去溶温度升高和乙醇浓度增大,分析物进炬速率增大,稀土元素谱线强度因此增大,去溶率也相应提高。与水溶液不去溶进样时相比,95％乙醇溶液预去溶进样时稀土元素的检出限降低十倍。 The glass concentric nebulizer with the desolvation unit, by adding ethanol to improve the injection efficiency. As the temperature of the solution increases and the ethanol concentration increases, the rate of the analyte advancing into the torch increases, resulting in an increase in the intensity of the rare earth element line and a corresponding increase in the desolvation ratio. The detection limit of rare earth elements decreased by a factor of ten when the 95% ethanol solution was predissolved in injections compared to when the aqueous solution did not desolventize.
