我用热电的(PQ EXCELL)型号的ICP-MS做痕量元素的分析,使用大约2个小时以后,反测前面的标准曲线的点,轻元素的信号下降的特别厉害,如Al等元素,前期测计数大约为4万左右,在2个小时以后变为25000左右,重金属元素信号下降也大约在10%-20%左右,我个人觉得信号的下降太大了,但不...
九、ICP-MS比较快的前处理方法,环境样品? 1. 采用微波炉消解。 2. 高压微波消解系统,MILLSTONE或CEM等等。 3. 微波消解或酸浸取.视样品和元素而定.如果作同位素丰度,用浸取就够了。 4. 看什么环境样品了,水样用酸固定就可以了,土壤是比较 难做的,不过微波消解也可以,按照你做的元素不同有不同的速度和方...

十一、最近我用的ELAN6000 ICP-MS本底很高,PB有10ppb的计数,Ni也很高。已经换了进样锥了,炬管也拆下洗过,雾化室也冲过,可计数就是下不来。进样的时侯高,不进样会低下来,应该不是气的干扰吧。进样的水应该没问题。 1. 建议重新优化仪器。 2. 检查一下...

In essence, the ICP-MS interface comprises of a step-down vacuum stage, located between a pair of conical metal plates, known as interface cones, in which small orifices have been drilled. The term "interface" is applied to the cones and the enclosed space (interface or "expansion" vacuum...
