一般描述
The innovative multi-pore technology is now also available in 3, 4 and 6 micron TSKgel SuperMultiporeHZ columns. Three columns, varying in linear range, are available. The base material of each TSKgel SuperMultiporeHZ column is poly(styrene/divinylbenzene). Particles in TSKgel SuperMultiporeHZ columns are mono-disperse in size and exhibit a broad range of pore sizes. Each particle, by design, has an extended linear calibration curve, thereby greatly diminishing chromatograms with inflection points. GPC chromatograms without inflection points . . . it will take some getting used to.
TSK-GEL H 系列凝胶渗透色谱柱在较广极性范围的多种溶剂中都很稳定。即便溶剂从甲苯变成甲醇，凝胶颗粒都不会膨胀或收缩。但这些色谱柱不能使用极性溶剂，比如水或水:甲醇混合物。5μm 的球形聚苯乙烯/二乙烯苯颗粒能为每根 30cm×7.8mm 内径的色谱柱提供的最低柱效为 16,000 个塔板数。有八种不同孔径的色谱柱可供选择，诸多的色谱柱对映分析分子量的范围从 G1000HHR色谱柱的约 2,000 道尔顿到 G7000HHR色谱柱的大于 10,000,000 道尔顿。柱床由四种填料混合形成的色谱柱 (H,L,M,N)，其特征在于扩展了分子量测定的范围，适于样品筛选或更多形式的分析。
