Symmetry色譜柱顯示出跨越多年的z越重現性,這來自于高純度硅膠顆粒、以及色譜柱行業內最嚴格的生產工藝與指標控制。
沒有其它硅膠色譜柱,能夠達到Symmetry色譜柱的柱與柱間、批與批間的重現性。
■ Symmetry C18 和 C8 色譜柱,提供z大程度的重現性
■ Symmetry Shield RP18 和 RP8 色譜柱,提供z越峰形
■ Symmetry 300 C18 和 C4 色譜柱,為肽與蛋白分析提供更好的峰形與回收率
1、杰出的峰形
當需要對堿性化合物分析獲得z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z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
2、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。
3、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。
