摘要:
以单硬脂酸甘油酯为固定相,用溶胶凝胶法研制出新的气相色谱毛细管柱,并检测了该毛细管柱的性能,包括色谱柱分离能力、柱效率、柱热稳定性、测定的重复性、固定相的极性、峰的对称性.色谱图1~4中各类化合物良好的分离表明此法制得的毛细管柱有较好的分离效果.它有较高的柱效,理论塔板数为2 900/m.此柱能耐高温,250℃时也能正常使用,此温度远高于用传统方法制备的同样固定相的商用色谱柱的使用温度120℃.该色谱柱稳定性好,10次测定的保留时间的相对标准偏差不大于0.26%.固定相的麦氏常数之和为496,显示为中等极性;分离色谱峰显示出良好的对称性,不对称因子测定值为1.
Abstract:
In th is paper the so-l g el techno logy is em ploy ed to prepareGC capillary co lum ns w ith g lycero lm on ostearate as sta tionary phase. The chrom a tog raph ic properties o f the co lumn are stud ied, including the sepa ra tion power, the co lumn e fficiency, the therm a l stab ility, the m easurement repeatab ility, the po larity o f the sta tiona ry phase and the symm etry of the peaks. In fig. 1~ 4 nice sepa ration o f va rious com pounds on th is co lumn is show ed. The column has good effic iency and the theo retical p late number is 2 900 /m. It can stand high temperature and can be used at temperature o f 250 ℃ that is much h ighe r than the allow ed max im um temperature o f 120 ℃ for the comm ercia l co lumn prepared by traditional m ethod w ith the sam e stationary phase. The RSD for 10 tim es o f m easu rem ents of the retention tim e is less than 0. 26%, wh ich m eans the co lum n has excellent repeatab ility. The sum of theM cReyno lds constants is 496, so the po larity of the stationary phase is m edium. The exce llen t peak-shape is proved by the fact that the asymm etr ic factor of the peaks is 1
