SymmetryShield色譜柱 WAT106151WATERS

杰出的峰形

當需要對堿性化合物分析獲得峰形時，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(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(通常可獲得USP拖尾因子不超過1.2)

• 與常規(guī)C18和C8柱相比，對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(xiàn)出不同的選擇性?？勺鳛櫸椒ㄩ_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溶劑、高比例水溶液的反相條件。具有內(nèi)嵌極性基團的反相顆粒能夠*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。
