用芯片式色谱柱代替传统的色谱柱实现了分离功能,结合色谱热力学原理分析了芯片式色谱柱中温度的影响,并以甲苯为例,通过实验确定随着芯片温度的变化,保留时间和峰高的变化规律。实验结果表明其能够较好地符合色谱热力学原理,能够替代传统的色谱柱实现分离功能,最佳工作温度在348~358K之间。 Chromatographic column chromatography instead of the traditional column to achieve the separation function, combined with the principle of chromatographic thermodynamics analysis of the temperature of the chip chromatography column, and toluene, for example, determined by experiments with the chip temperature changes, retention time and peak High variation. Experimental results show that it can better meet the chromatographic thermodynamic principle, can replace the traditional column to achieve separation, the best working temperature between 348 ~ 358K.
