Waters Symmetry RP18色譜柱186000112
Symmetry®色譜柱的zui主要優(yōu)勢是重現(xiàn)性好，此系列色譜柱使用高純度原料，經過嚴密控制的填料生產流程和色譜柱裝填技術，得到了市場上重現(xiàn)性的高效液相色譜柱。同時有Symmetry 卡套柱和保護柱供選擇。
Waters Symmetry RP18色譜柱186000112高純硅膠保障色譜峰形
基于礦物原料的傳統(tǒng)硅膠反相柱填料都含一定量的金屬雜質如鐵和鋁等，這些雜質會導致硅膠表面活性增加，使堿性化合物和螯合物的色譜峰嚴重拖尾。這不僅加大了此類物質HPLC方法開發(fā)的難度，而且會影響分析結果的準確度和重現(xiàn)性。
Symmetry®系列色譜柱是*以化學合成方式制造的高純硅膠反相柱。其超低的金屬雜質含量結合沃特世專有的化學鍵合和端基封尾技術，保證了Symmetry®系列色譜柱對堿性化合物和螯合物的良好峰形。
極性基團嵌入技術
優(yōu)化色譜峰形和分離選擇性
極性基團嵌入技術又稱屏蔽型固定相技術，是在通常的C18／C8鏈中引入特定的極性基團所得到的新型固定相。大量研究表明，極性官能團可有效阻擋有機堿與硅膠表面殘余硅羥基的不良作用，因而其峰形比相應的C18／C8柱更優(yōu)。同時，這類固定相允許使用全水流動相而不會發(fā)生“相塌陷”現(xiàn)象，因而可用于分離許多親水性化合物。
SymmetryShieldTM RP18／RP8系列色譜柱是以沃特世*的一步合成技術制造的屏蔽型固定相。它可以顯著改善堿性化合物峰形，并且提供與C18／C8柱不同的分離選擇性。
