美国能源部太平洋西北实验室开发出质谱仪与电泳技术联用的高精确超微量分析技术,称为毛细管区电泳质谱技术。采样仅需十亿分之一升,放在高电场下的毛细管中使之产生离
The Pacific Northwest Laboratory of the US Department of Energy has developed a high-precision, ultra-micro-analytical technique for mass spectrometry coupled with electrophoresis technology called capillary zone electrophoresis mass spectrometry. Sampling only needs one billionth of a liter, leaving it in the capillary under a high electric field
