多毛细管柱色谱

Multicapillary Columns for Chromatography

应用直径范围为5～50μm的毛细管色谱柱可以使分离速度最大化。然而它们所需要的样品量很小,以至于难以进样和检测。本文设计的多毛细管柱克服了单毛细管柱在流速、体积、样品容量等方面的限制,并且可以与所有的常规色谱设备兼容。

Using capillary chromatography columns with diameters in the range of 5-50μm maximizes their speed of operation. However, they require very small sample volumes that are difficult to inject and detect. The multicapillary design described in this paper overcomes the flow rate, volume, and sample capacity limitations associated with single-capillary columns. Moreover, the multicapillary column is compatible with all common chromatographic equipment.
