Symmetry Shield色譜柱
杰出的峰形
當(dāng)需要對(duì)堿性化合物分析獲得峰形時(shí)，SymmetryShield色譜柱是的選擇。該反相色譜柱基于沃特世內(nèi)嵌極性基團(tuán)技術(shù)，這項(xiàng)技術(shù)確實(shí)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。
因此，SymmetryShield色譜柱能夠：
· pH2-8范圍內(nèi)使峰形與分離度顯著改善(通?？色@得USP拖尾因子不超過1.2)
· 與常規(guī)C18和C8柱相比，對(duì)堿性化合物的保留較小
選擇性
SymmetryShield色譜柱，與常規(guī)C18和C8柱相比，因?yàn)楣璐蓟钚暂^低，對(duì)于堿性化合物的保留也就較弱，從而呈現(xiàn)出不同的選擇性，可作為方法開發(fā)工具。
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(dòng)相條件下獲得穩(wěn)定的保留，以及杰出的峰形。
