Symmetry Shield色譜柱
杰出的峰形
當需要對堿性化合物分析獲得卓越峰形時,SymmetryShield色譜柱是極好的選擇。該反相色譜柱基于沃特世專利內嵌極性基團技術,這項技術確實能夠“屏蔽”(shield,英文有“護罩”、“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生拖尾作用。
因此,SymmetryShield色譜柱能夠:
· pH2-8范圍內使峰形與分離度顯著改善(通常可獲得USP拖尾因子不超過1.2)
· 與常規C18和C8柱相比,對堿性化合物的保留較小
獨特選擇性
SymmetryShield色譜柱,與常規C18和C8柱相比,因為硅醇基活性較低,對于堿性化合物的保留也就較弱,從而呈現出不同的選擇性,可作為方法開發工具。
完美兼容高水相條件
SymmetryShield色譜柱還特別適用于那些要求使用低比例有機溶劑、高比例水溶液的反相條件。具有內嵌極性基團的反相顆粒能夠完全被水浸潤,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定的保留,以及杰出的峰形。
