ACQUITY UPLC 颗粒技术
UPLC®颗粒*不同于常规HPLC 填料颗粒，它需要经过UPLC测试和认证并且能够耐受UPLC操作压力（如 15000 psi/1000 bar）。为什么颗粒的耐压性能如此重要? 为了实现亚2 µm颗粒的高柱效，需要使用更高的线速度（即更高流速），这种情况下会产生更高的操作压力。沃特世公司已经推出了两种高效耐压的UPLC 颗粒：
1.7 µm亚乙基桥杂化（BEH）颗粒
1.8 µm高强度硅胶（HSS）颗粒
首先推出的是1.7 µm ACQUITY UPLC® BEH 颗粒。它采用第二代杂化颗粒技术，是UPLC 技术背后的核心之一，包括五种色谱柱化学品：
C18
C8
Shield RP18
苯基
HILIC
由于它是杂化颗粒，更宽的pH 值适用范围（pH 1-12） 使得方法开发快速简便。BEH颗粒也有HPLC 颗粒尺寸（2.5, 3.5, 5 和 10 µm），用在XBridge™ 系列HPLC色谱柱上，这样可以达到从HPLC 到UPLC分离方法无缝转换。
第二种是沃特世公司推出的1.8µm的ACQUITY UPLC HSS（高强度硅胶）颗粒。随着更多的分离科学家意识到超高效液相色谱UPLC技术在不同应用领域的优势，沃特世公司继续生产更多的ACQUITY UPLC 颗粒和化学品解决方案来满足不同的应用需求。沃特世公司的材料科学家开发了高强度硅胶（HSS） 颗粒，具有高机械稳定性和恰当的形态，以满足长柱寿命和超高效液相色谱UPLC在高至15000 psi （1000 bar）的压力下的工作效率。这种1.8 µm微米的超高效液相色谱 UPLC高强度硅胶 HSS 颗粒为UPLC分离而设计并经特别测试，包括两种色谱柱化学品。
T3 C18
为保留和分离极性有机化合物而设计，低键合密度反相C18 柱，100%纯水相流动相兼容，与Atlantis® T3 HPLC高效液相色谱柱类似。 的ACQUITY UPLC 键合相，ACQUITY UPLC HSS C18 色谱柱为碱性化合物的分离提供的峰形，与ACQUITY UPLC BEH C18 色谱柱相比，有教强的保留，并且在低pH值具有相当长的色谱柱寿命。
