文章研究了0.5%OV-17涂渍硅烷玻璃微球柱在低压下的色谱行为,并与其在常压下的特性相比较,有更快的分析速度,更低的柱温且其灵敏度有很大提高犤1犦,分离度亦有所改善。从热力学方面测出OV-17涂渍柱低压下的X1,1n(a1/w1)∞△G1∞比常压下有所减小,且与保留时间变化一致。 In this paper, the chromatographic behavior of 0.5% OV-17 coated silane glass microspheres under low pressure is studied and compared with the properties under normal pressure, the analysis speed is faster, the column temperature is lower and the sensitivity is very good Large increase 犤 1 犦, the degree of separation also improved. Thermodynamics measured OV-17 coated column under the low pressure X1,1n (a1 / w1) ∞ △ G1∞ than normal pressure decreased, and consistent with changes in retention time.
