不同寻常的Eternity

Eternity翻译为中文是永恒的意思！Eternity系列色谱柱是kromasil色谱柱的高端系列。Eternity系列的品质更加卓越，当然价格也更加昂贵。Eternity系列是kromasil的专利产品，是一种长寿命的色谱柱！
Eternity系列的特点是：
The silca matrix
The Eternity platform is based on the Kromasil 100A silca matrix,well known for high mechanical stability, and a well-defined pore structure.
The organosilane interfacial gradient
The silica matrix is bonded using a patent-pending technology.An organosilane is immobilized on the silica, and, under certain proprietary conditions merged into an organic/inorganic interfacial gradient.The pores are virtually returned to their original size,resulting in a surface exhibiting both organic and inorganic moieties.This process step has been fine-tuned to give Kromasil EternityXT its extreme chemical stability,extending the pH range and packing lifetime.
The finished product
Finally the product is functionalized with various surface chemistries ,followed by a proprietary endcapping process.
  这段话原汁原味的表达了Eternity色谱柱的特点，简言之就是，硅胶粒径合理，多孔硅胶的制备使用了专利技术，合理的键合和封端技术。从而延长了pH范围和色谱柱的使用时间。再简言之，就是结构决定性质。色谱柱生产过程中的各个工艺都做的非常精细。色谱柱看似相同，其不同之处在于细微之处的某些专利，有些时候这种专利技术是非常牛气的！
  相比于Classic系列，Eternity的系列种类还是比较少的。我觉得各位想提高色谱柱使用寿命的朋友不妨选择Eternity系列，或许可以解决色谱柱不耐用的难题。如果您有不同的见解与看法，欢迎批评指正！
