Waters Symmetry RP18色譜柱186000112
Symmetry®色譜柱的zui主要優勢是重現性好，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方法開發的難度，而且會影響分析結果的準確度和重現性。
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。同時，這類固定相允許使用全水流動相而不會發生“相塌陷”現象，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。
