ACE Excel 2µm columns are available with C18-PFP and C18-AR “Extra Resolving Power” phases. These two unique phases offer multiple mechanisms of separation and have been specifically developed to provide alternative selectivity to C18 phases. ACE Excel 2µm columns are also available with C18, C8, C4, CN, AQ, Phenyl and Silica phases.

它适合于1.7um,2um,3um以及5um等合种粒径的产品，所有的产品是以货号“EXL-”。 也就是ACE Excel系列。 ACE的UHPLC/HPLC兼容的高压柱管所填装的产品（货号EXL-开头）可以完全取代HPLC柱管填装的同等固定相产品（货号ACE-开头）。 不改变分离与保留行为。 很多客人会问，例如同是C18-AR 3μ 150X4.6MM色谱柱，为什么ACE色谱柱会有ACE-119-1546和EXL-119-1546U两种货号呢？

Avantor® ACE® Excel® C18-PFP phase utilizes a specially developed ligand combining a C18 chain with integral PFP functionality. This results in a phase that maintains the hydrophobic, stability and low bleed characteristics of leading C18 phases, yet provides the multiple retention mechanisms of a PFP phase.

PFP分离机制 ACE C18-PFP相显示有多个保留机制，包括疏水性、π-π相互作用、偶极-偶极、氢键和形状选择性。 虽然下述部分提供了相对强度的近似值，但每个保留机制的优势由溶质的物理/化学性质、其结构和所采用的色谱条件决定。 PFP环在相的表面上加入了芳香特性。 然而，PFP相不同于苯基相，因为电负性氟原子会产生缺电子的苯环，使得PFP相可以作为路易斯酸而起作用。 这将与能够给出电子的分析物（即路易斯碱）相互作用。 这与苯基相相反，苯基相 …
