Waters 色譜柱-Symmetry分析柱

These reversed-phase columns contain Waters patented embedded polar group technology that “shields” the silica’ residual silanol surface from highly basic analytes. The reduced silanol activity for the SymmetryShield RP8 column significantly improves peak shape and resolution..

SymmetryShield色譜柱
杰出的峰形
當(dāng)需要對堿性化合物分析獲得峰形時，SymmetryShield色譜柱是極
好的選擇。該反相色譜柱基于沃特世內(nèi)嵌極性基團(tuán)技術(shù)，這項
技術(shù)確實能夠“屏蔽”(shield，英文有“護(hù)罩”、“屏蔽”的含義)硅膠表面
的殘留硅醇基，使它不能與堿性較大的化合物發(fā)生拖尾作用。*兼容高水相條件
SymmetryShield色譜柱還特別適用于那些要求使用低比例有機(jī)溶劑、
高比例水溶液的反相條件。具有內(nèi)嵌極性基團(tuán)的反相顆粒能夠*
被水浸潤，從而確保顆粒與樣品之間的更好的相互作用。從而在高
水相流動相條件下獲得穩(wěn)定的保留，以及杰出的峰形。Symmetry和SymmetryShield分析柱
