好不好给出上下文的？？

Dedicated sample concentration schemes for neutral compounds have been developed for MEKC. They may be generally classified into on-capillary mode and off-capillary mode. On-capillary sample concentration techniques are of highly preferred since they are simple in operation, time-saving and less vulnerable to sample loss and concentration. Therefore, there have been intensive studies on on-capillary sample concentration approaches for neutral compounds in MEKC

最好放到专业英语版块去，否则设这个做什么？？

哦,晓得了,谢谢

on-capillary mode ：在柱模式
off-capillary mode：离柱模式
本文主要讲毛细管电泳中的一些样品浓缩方式。本文说到的MEKC中的“on capillary mode”主要指sweeping吧！
而离柱的预浓缩方法就很多了，如固相微萃取（SME）

是不是就是on-line capillary 和off-line capillary？？柱上和柱外

谢谢了

到英语专业翻译转转吧，

又掌握了个方法
谢谢
