For that the separation and preconcentration of the samples before the analyce is requisite.
因此,对待测样品进行分离富集预处理是不可缺少的重要环节。
The method provided good reproducibility in terms of both migration time and peak height. It can be successfully used for the preconcentration zwitterion.
这种方法有很好的重现性,能够成功地用于两性离子的预富集。
The latter has been packed into the micro-columns, which was used in the FI-AA systems; on-line preconcentration and separation of precious metals have been achieved.
将后者填充于FI-AA联用的微型柱内，实现了贵金属的自动在线预浓集与测定。
